where n is the amount of things
make sure when you find the median you are going in numbers of increasing order - 3how do you find where the median is for an even amount of things?The median for an even amount of things is the average of the two middle numbers. But what are the 2 numbers? The first middle number is at n/2 the second middle number is the number to the right of it. so let's say you have 100 numbers the first middle number is at 100/2 =50 and the 2nd middle number is the 51st number since it is to the right of 50
- 4What is the mode?The most common number
- 5How do you find the mean for the following list 5,6,2,2,2,7Add up all the numbers and divide by however many numbers there are.
- 6What is the Median? What is the Range? What is the min? What is the max?Median is about 82, 81,83 are also acceptable kind of hard to see on this graph
Range is 130-25=105
Min is 25
Max is 130
- 7Which graph has a higher standard deviation?The standard Deviation is a measure of how spread out a list of number is. You don't need to find the exact standard deviation on the SAT but estimate it instead. The closer the numbers are to the mean the lower the standard deviation is. that is why the 2nd graph has a higher standard deviation.
- 8What is the mean?The frequency tells you how many times a number occurs so the mean is found by
- 9—863 Italy
there are nine countries so the median is at (9+1)/2 =5 so the median is at the 5th country in increasing order which is Italy
