Question 44 pts

A 2 X 3 X 4 X 5 X 6 factorial design has:

720 independent variables

3 independent variables

5 independent variables

1 independent variable

Answer 1

Solution :-

Here we have to find out that how many independent variables are there in factorial design.

Here we know that, Number of independent variables = Number of digits in the factorial design.

In factorial design we have, 5 digits. i.e, 2,3,4,5,6.

i.e, 5 independent variables are 2,3,4,5,6.

Here, means, it has 5 independent variables with 2,3,4,5,6 levels respectively. ( value of each digit = number of each levels in each independent variable)

Hence, factorial design has 5 independent variables.
