Hello class and welcome back to the third term of your APDD education!
I'm really excited to start up a new course! Another announcement of mine includes some new content for all APDD students and the APDD community.
I have set up a website for my overall organisation; VariousStudies! Here's the link: https://variousstudies.wixsite.com/variousstudies
There's a lot of other sites I have made connected to that one, but the VariousStudies website is the main website I have created for the organisation, the head quarters if you wish.
I also want to announce that the keywords we have learnt in the first course are NOT official and do NOT have to be used! It is just a brief term to cover the majority of it's definition, so if you see someone saying 'End Task' instead of 'End', please do not correct them as they are using a simple umbrella term.
Alright, that's it! Please enjoy your day!
Types of Graphs
Hello and welcome, class! Today we will be looking at types of graphs or charts.
1. Line Charts
I would recommend line charts for investigating trends, such as 'How many people play basketball in the last 2 years?' or something similar to that. Line charts can be sometimes difficult to read for a beginner, therefore I would only recommend using this chart if you are very confident with APDD.
2. Bar Graphs
This is the most used type of graph in the APDD community, as it is clear, straight to the point and easy to read. Bright (but not too contrasting and saturated) colours are also very important with bar graphs, as it makes it even more easy to read. This is recommended if you want to get straight with the point with the general and overall data.
3. Pie Charts
This sort of chart is a bit harder to make as you need to calculate the sizes of the sections of the percentages on the pie chart. Again, this type of graph is useful when you only want to see the overall data, just like the bar graph.
I would not recommend this type of graph at all, as it usually looks messy and unprofessional. Please do not use this one for homework or exams!!
Treemaps are a very creative way of presenting data, but for some beginner students in APDD it may be hard to understand or get a grasp of. I wouldn't particularly recommend this myself, but individuals may think otherwise.
6. Area Charts
Area charts can be hard to figure out at first, but as you look at it more you may figure it out. I wouldn't recommend this one but you are free to use it if that's your choice.
Which type of graph do you prefer?
I hope to see you next lesson!
Basics of Bar Graphs
Hello, class! Today we will the tackling the topic of bar graphs. Now, we are not going to be focusing on the other graphs [until future, more advanced courses] because bar graphs are the main chart or graph type in the APDD Community. We will be learning the basics of bar graphs and the information they can and cannot show. Let's get into it!
[Note: Please take notes as you will need them for future bar graph homework, and the upcoming exam!]
Bar graphs use horizontal or vertical rectangles to measure data. The rectangle [also known as the 'bar'] goes up to the point where it gets to the appropriate level. The bars make comparisons to eachother, making the data easy to read. Something that I would not recommend for bar graphs is showing 'trends', line graphs are more suited to that form of data.
Examples of Bar Charts

How to Make a Bar Graph
Hello and welcome back, class! Today we'll be looking at how to make and create a bar graph. I will be demonstrating how to make a vertical bar graph.
1. Decide on a title. In this case, the title will be based on your subject for your flowchart in an APDD Investigation. (For example, What Colour Are You?)
2. Draw the horizontal and vertical axis (the lines on the left and bottom of your chart).
3. Label the horizontal axis. (For example, 'Colour'.)
4. Above the horizontal axis's label, label the bars (for example orange, blue, red, etc.).
5. Label the vertical axis. (For example, 'Number of People'.)
6. Decide on the scale. What is the least greatest number on the scale, and which is the greatest? In what range will the numbers go in? (For example, the least greatest number is 0 and the greatest number is 30. 0 + 5 = 10, 10 + 5 = 15, etc.)
7. Draw a bar for each label, with different colours to make it easy to tell apart data.
Interpreting the Data
After creating the bar graph to full effort, you can step back and take notes on important aspects of the data.
1. Outliers. Outliers are data that often come far away from the average or most frequent piece of data, for example '30 people' would be an outlier because the average data is far below it, being '10 people'.
2. Gaps. Look for gaps in the data, for example '0 people like the colour white' would be a gap because there is no data for the colour white.
3. Frequency. Look for frequency in certain data, for example the most common occurrence would be 10 people liking a colour.
Remember to take notes on these data types. They will be very important on creating the conclusion (which is what we'll touch on in the next course).
How to Read a Bar Graph
Hello, class! Today we will be looking at how to read a VERTICAL bar graph. These methods could pretty much work on a line graph, but please remember we are focusing on bar graphs!
1. Read the title, labels of the horizontal axis and labels of the vertical axis. These can tell you the first off basics of the chart; what the graph is about, etc.
2. Check the scale for the vertical axis. You will want to be able to calculate how many of this and that by observing the scale and range on the vertical axis.
3. Locate the label on the horizontal axis you want the most information from. The label for each bar graph will be on the horizontal axis. Locate the one you want the most information from.
4. Read directly up from that label to the top of the bar. Then look directly to the left to see the vertical axis. Whatever the quantity is, is your answer.
Congratulations, you now know how to read a bar graph!
Combining Bar Graphs and Line Graphs
Hello, class! Today we will be learning about combining bar graphs and line graphs! It may seem odd, but it is in fact a real thing that people all over the world commonly use.
The title is just as it sounds; we combine a bar graph and a line graph. Here's a good example of one: http://www.ciese.org/curriculum/weatherproj2/images/graph_combo.gif.
It may look big and scary and complicated, but as we progress you will see it really isn't.
As you can see, there is an added vertical axis! This time the title is 'Temperature (°C)'. You read the line graph with the scale on the right hand side vertical axis! It looks simple now, right? And as you expect, you read the bar graphs with the left hand vertical axis.
You would make this the way you make a bar graph, just add a few extra steps to add in another vertical axis, draw in the line graph, and you're done!
If you were wondering, there is no specific name for this type of graph. However, I personally like to call it a 'Bar and Line Graph Combo'.
X Axis and Y Axis
You may use the term 'X axis' instead of 'horizontal axis' and 'Y axis' instead of 'vertical axis'. However, the terms 'vertical axis' and 'horizontal axis' are there to help you learn the key terms. Therefore, I would only recommend using the terms 'Y axis' and 'X axis' when you are more advanced in APDD, and are more comfortable and knowing with / of the key terms.
Bar Graph Key Terms
Hello, class! Today we will be revisiting everything we have learnt about bar graphs and observing our key terms. Our key terms are our most important words and aspects of our bar graphs.
Title - The title will be what you name your bar graph. The title is often based off of your subject of your flowchart that you made for an investigation.
Horizontal Axis / X Axis - The horizontal line on a bar graph, usually 'holding' the bars on the bar graph.
Vertical Axis / Y Axis - The vertical line on a bar graph, usually showing you the scale on the bar graph.
Horizontal Axis Title - What you name your horizontal axis, such as 'Colour' or 'Animals'.
Vertical Axis Title - What you name your vertical axis, such as 'Quantity'.
Scale - The quantity, often on the vertical axis.
Bar Labels - The labels you give the bars on the bar graph, such as 'Orange' or 'Blue'.
Bar and Line Graph Combo - The combination of a bar and line graph.
1. Create a bar graph based on data you have made up. It HAS to be a bar graph and it HAS to be vertical.
2. Become a member of this group: https://www.goconqr.com/en-GB/groups/65081
3. Comment your bar graph or a link to it using http://postimages.org on the discussion https://www.goconqr.com/en-GB/status_updates/8725931.
Thank you and please do your homework! Have a great day!
APDD Chart Basics Revision
Hello class, and today we will be focusing on our exam revision.
It has been a very short term, however we have learnt a lot and hopefully you are ready to start revising for your course exams.
There are two course exams: The quiz exam and the chart exam.
In the quiz exam you will have to answer questions about what you learnt this term.
In the chart exam you will have to make up your own data and create a bar and line graph combo.
The next two modules will be dedicated to the quiz exam and the one after that will be dedicated to the chart exam.
Have a great day and please remember to revise for your exams!
IMPORTANT For Entering Your Exam!!
Hello, class! I am so glad you made it through the exam. Now, please follow these instructions to enter the exam.
1. Become a member of this group: https://www.goconqr.com/en-GB/groups/65081. We will respond with the invite shortly.
2. State on this status update (https://www.goconqr.com/en-GB/status_updates/8766950) your result to the APDD chart exam. Please do not lie! I will be checking the statistics of the quiz anyway, so you will most likely get caught. If you don't want others to know your score, please state in the comment, that you will [shortly] post, that you wish for the comment to be deleted after I have observed it. Thank you!
APDD Chart Basics Exam 2 Instructions
Hello, everyone! Today we will be going through the instructions for entering the APDD chart basics exam 2. In this exam, you will be creating your own bar and line graph combo with data you have made up yourself.
1. Make up your own data. This can be based or not based off of a poll; it doesn't really matter! Just please, check that your made up data is sensible. Also, the data has to be applicable for a bar and line graph combo.
2. Create the bar and line graph combo! Be sure to follow the instructions of how to make one that you wrote in your notes; it is very important that you actually know how to create one.
3. Become a member of this group: https://www.goconqr.com/en-GB/groups/65081. We will respond shortly.
4. Upload your finished bar and line graph combo to http://postimages.org.
5. Comment a link to your image on postimages.org on the following status update: https://www.goconqr.com/en-GB/status_updates/8767039
Farewell!Hello, class! But that will soon turn into a 'goodbye', as this is our final module in the course.
Don't worry, I will be creating a new one very shortly! However, the next course might be the final one; or the one after that, I haven't really decided properly yet.
The course will be called 'Creating Conclusions in APDDI ' and it will be focused on the last step of the APDD Investigation process: Creating the conclusion!
It may seem simple and even maybe irrelevant to some of you, but I promise you, it is extremely interesting! In fact, one of my favourite steps in the APDDI process is creating the conclusion; a close second to creating the chart.
So, I all wish you a happy holiday! Stay safe!
