Question

find the range, variance, and standard deviation for the given sample data, if possible if the measures of variation can be obtained for these values, do the results make sense? 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 ( 1 = ) smooth yellow, ( 2 = ) smooth green, ( 3 = ) wrinkled yellow, and ( 4 = ) wrinkled - green. ( 2 1 3 1 3 1 4 1 2 2 2 1 1 2 2 2 2 2 2 ) b. the standard deviation of the sample data cannot be calculated can the variance of the sample data be obtained for these values? choose the correct answer below and, if necessary, fill in the answer box within your choice. a. the variance of the sample data is (round to one decimal place as needed ) b. the variance of the sample data cannot be calculated

Explanation:

Step1: Analyze the nature of data

The phenotype codes (1 = smooth yellow, 2 = smooth - green, 3 = wrinkled yellow, 4 = wrinkled - green) are nominal data. Nominal data are used for categorization, and operations like finding the variance (which is based on the arithmetic mean and differences from the mean) are not meaningful for nominal data.

Answer:

B. The variance of the sample data cannot be calculated
