Question

Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype​ codes, where 1equals​smooth-yellow, 2equals​smooth-green, 3equalswrinkled ​yellow, and 4equals​wrinkled-green. 2    1    2    2    3    1    4    2    2    2    2    2    2    2    2    3    1    2    2    2 find the standard deviation of the sample data

Answer 1

Range: Highest Data Value - Lowest Data Value

= 4 - 1 = 3

Finding Mean:

Sum of all Values divided by the total number of Values

Finding Variance:

Variance is the Sum of Squared Deviations From the Mean, divided by n -1, where n is total number of values.

Finding Standard Deviation:

Standard Deviation is the Square Root of Variance.

s = = 0.613
