Question

A researcher has a table of data with 5 column variables and 4 row variables. The value for the degrees of freedom in order to calculate the x squared statistic is:

12

20

4

19

Answer 1

Answer:

Given data :

number of column variables = 5

number of   row variables. = 4

Now, we have to find out the:

The value for the degrees of freedom in order to calculate the x squared statistic :

We know, the formula for the degree of freedom is ,

degree of freedom =  ( row -1 ) ( column -1)  

= ( 4-1) (5-1)

= (3) ( 4)

= 12

$\therefore$ Degree of freedom =12

From the question, "option a" is correct .

Option a is 12
