6. The factors that affect corals survival are the temperature of the water, the water depth, how active the waves are.
Will the Coral Survive
Probability is a way to measure the chances that something will occur in relations to the possible alternative

Variance σ2
The variance (s2) is calculated as:
Variance is a value that is used in Statistics to describe how far away your data sets are from the mean.
∑=sum
X=mean of the value
n=number of numbers
s2= Variance X=each data value

Slandered Deviation
Standard Deviation σ
Standard Deviation describes how spread out the data are.
∑=sum
X=mean of the value
n=number of numbers
σ= Standard Deviation
X=each data value

9. Theoretical Distribution(TDC)
It is an ideal picture of a distribution based upon a sampling

10. T-Test Equation
The P value has to be less than 0.05 to reject the null
