in general, what is the effect of an increase in the variance for the sample of difference scores? group of answer choices a decrease in the standard error and a decrease in the value of t an increase in the standard error and a decrease in the value of t a decrease in the standard error and an increase in the value of t an increase in the standard error and an increase in the value of t

Answer :

Option 2 is correct that is an increase in the standard error and a decrease in the value of t.

Given that,

Set of potential solutions a decline in the value of t and a reduction in the standard error a rise in the standard error and a fall in the t value an increase in the value of t and a drop in the standard error a rise in the value of t and an increase in the standard error.

The standard error is obtained by taking the variance's square root. The standard error rises as the variance does. Since the standard error appears in the t statistic's denominator, its value lowers as the standard error rises.

Therefore, Option 2 is correct that is an increase in the standard error and a decrease in the value of t.
