1Why are measurements and observations displayed in tables?When they are displayed in tables they are more understandable and easier to read.
2What can Spreadsheets be programmed to do?Spreadsheets can automatically calculate values ; averages .
3Define the word discrete from discrete groupings?Discrete groupings are observations that can be sorted into definite categories
and counted.
4Define the word continuous?Measurements involving numbers aren't discrete but continuous. This means that if you choose two numbers you can always find other numbers in between.
5What are some examples of continuous measurements?Examples of continuous measurements include age, mass, length, volume, temperature and human height.
6Discrete groupings can construct different types of graphs name them.Discrete groupings can only construct
pie or sector graphs.
7Line graphs require two sets of measurements that show continuous variation. What are they?The two sets of measurements are
the horizontal and vertical axes.
8What's the difference between line graphs and lines of best fit?Line graphs connect trough different points and lines of best fit go roughly through all the points.
9What do Scientists need to do during an experiment to make it useful?Scientists need to a scientific report to explain how they ran the experiment, what they measured and how they interpreted the results.
10How do tables and graphs help scientists when they do their experiments?Tables and graphs help scientists
display patterns in their measurements.
11What types of graphs are used when you have a set of discrete observations?Bar and column graphs show discrete values .
12What is shown in a pie or sector graph?A pie or sector graph shows
proportions of each grouping within an total. The whole pie or sector graph
represents 100%.
13What are the different types of line graphs?Line of best fit and curve of
best fit.
14What can a graph do that table cannot?A graph can show trends
more clearly than
tables can.
15What makes an experiment complete?An experiment will be complete when using some way or another you communicate with other scientists.
16What computer program can enable you produce a digital table or a spreadsheet?A spreadsheet can enable you to
produce computer programs such as Microsoft and excel e.t.c..
17Apart from enabling computer programs what else can a spreadsheet do?A spreadsheet can also use scientist's measurements to construct different
types of graphs.
18When discrete groups are categorized are measurements possible between each of the categories?No measurements are possible
between each of the
categories.
19Bar and column graphs have discrete values, but what is displayed from the graphs?The discrete values display the horizontal and vertical axes on the graphs.
20Once you have plotted all the points on a line graph there are two ways to connect the points. What are they?They two ways are curve of best fit
and line of best fit.
