Question

Exhibit 13-4 In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments. The following information is provided. ​ SSTR = 200 (Sum Square Between Treatments) SST = 800 (Total Sum Square) Refer to Exhibit 13-4. The number of degrees of freedom corresponding to between treatments is _____. Group of answer choices 59 4 5 60

Answer 1

Answer:  4

Step-by-step explanation:

In performing AVOVA (Analysis of variance)

The number of degrees of freedom corresponding to between treatments  = n- 1 , where n = number of treatments

As per given information, we have

The total number of treatments in the experimental design= 5

i.e. n=5

Then, the number of degrees of freedom corresponding to between treatments = 5-1=4

Hence, the correct answer is "4".
