For a repeated-measures study comparing two treatment conditions, a researcher obtains a sample of n = 9 difference scores with a mean of MD = 4 and a variance of s2 = 36. What is the value for the repeated-measures t statistic for these data?​

Respuesta :

Answer:

Step-by-step explanation:

Given that for a repeated measures study comparing two treatment conditions, an experiment was conducted.

n=9:  Mean difference =4:

Variance = s^2 =36

Std error = [tex]\frac{s}{\sqrt{n} } =\frac{6}{3} \\=2[/tex]

t statistic = Mean diff/SE

= [tex]\frac{4}{2} =2[/tex]
