Variance Two values that are used in statistics to describe how far away your data are from the mean are Variance and Standard deviation. Set 1: 8,9,10,11,12 Set 2: 1,2,10,17,20 In the first set,there is not much variation away from the mean. In the second set the other values are farther away from the mean.

Standard Deviation One standard deviation is considered the numerical distance away from the mean in the positive and negative direction. So we say that it is plus or minus some number away from the mean.

Chi-square The chi-square test can be used to see if there are any significant difference between data sites or sources. We will use the chi-square test to determine if there are any significant differences between survival rates at our “SEA TURTLE BEACH SITES” when we play the SEA TURTLE GAME.

T-TEST THE T-TEST EQUATION CAN BE USE TO CALCULATE THE T-STATISTIC IS ONE DESINGNED TO TEST WHETHER THERE IS A SIGNIFICANT DIFFERENCE BETWEEN THE MEANS OF TWO INDEPENDENT SAMPLES THOSE OF YOUR (1) TREATMENT AND (2) CONTROL GROUPS.
