4 out of my __ coral polyps survived.


Standard deviation variance
Standard Deviation &Variance

Variance= how close together a group of data is from the mean.

Standard Deviation= the square root of the variance.



Butterfly pupation project
Butterfly Pupation Project

Chi-square Value: 3.24 compared w/ 3.84 from Chi-square table at 1 DF.

Above: S= Survived///D= Died

Bellow: Overall Survival Rate 59.4%  There was no significant difference but it was so close that it would be worth it to do the same experiment with hundreds or even thousands of samples.
