T-test
An analysis technique employed to assess whether there is a significant difference between the average values of two distinct groups.
Participants

Final Answer :
A
Explanation :
The degrees of freedom (df) for a t-test for independent means is calculated as n1 + n2 - 2, where n1 and n2 are the sample sizes of the two groups. Given that df = 24, solving for n1 + n2 gives us 26 participants in total.
