Question

a researcher wishes to design a fully blocked experiment with groups of subjects representing every possible combination of 1 explanatory variable and 5 other variables for a total of 6 variables. how many blocks will there be in her experiment?

Answer 1

You have 6 variables with 2 levels each. Thus 2*2*2*2*2*2 or 2^6 or 64. 

Answer 2

Answer: There are 64 blocks will be present in her experiment.

Explanation:

Since we have given that

Number of explanatory variable = 1

Number of other variable = 5

Total number of variable = 6

Since there are two types of variable given.

so, the number of blocks in her experiment would be

`2* 2* 2* 2* 2* 2\\\\=2^6\\\\=64`

Hence, there are 64 blocks will be present in her experiment.
