6. Variation
Variance (s2) is two values that are used in statistics to describe how far away your data are from the mean is variance and standard deviation.
Set 1: 8,9,10,11, set 1 isnt far from the mean
Set 2: 1,2,10,17, set 2 is far from mean

7. Standard Deviation Describes how spread out the data are.
The sq. root of variance.
Sq.root of 10.8 = 3.3=σ

8. Theoretical Distribution

9. Chi-square
The chi-square test can be used to see if there are any significant differences between data sites or sources.
Chi-Square formula:χ2= ∑(observed-predicted)2
Predicted

10. The t-test
The t-test equation can be used to calculate the t-statistic is one designed to test whether there is a significant difference between the means of two independent samples.
