Question

Dr. Wu is investigating the effect of color on happiness. She found the following: purple (M = 95) scored higher than red (M= 75) scored higher than blue (M = 50), F(2, 57) = 13.28, p < .001. Which of the following do we know?

Group of answer choices

Purple scored significantly higher than red

Red scored significantly higher than blue

All of the above

Answer 1

Given that Dr. Wu is investigating the effect of color on happiness. She found the that purple (M = 95) scored higher than red (M= 75) scored higher than blue (M = 50), F(2, 57) = 13.28, p < .001

Since the value or the significant value is very low ,even less than 0.001

So the result is very significant this means

So the null hypothesis of equal difference is rejected and statistically can be concluded that the effect of colour on score differ signicantly.

So the correct answer is " All the Above".
