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 1 = smooth-yellow, 2 = smooth-green, 3 = wrinkled yellow, and 4 = wrinkled-green. Can the measures of variation be obtained for these values? Do the results make sense?

Answer 1

Answer: using this as the data

1 1 4 4 1 4 1 1 3 2 2 2 1 2

(a). The mean phenotype code is 2.1

(b). The median phenotype code is 2

(c). The mode phenotype code is 1

(d). The midrange of the phenotype codes is 2.5
