Hypothesis and analysis plan
We will exclude participants who incorrectly answer an attention check item that requires them to recall which team was rated as more qualified (the answer is always Team A).
We will compare participants’ ratings of Team B between the two conditions using an independent samples t-test.
We expect that participants will rate Team B as significantly less qualified when Team B is described as less qualified than Team A than when Team A is described as more Qualified than Team B.
This will be done with the following code:
T-TEST GROUPS=worse(0 1)
/MISSING=ANALYSIS
/VARIABLES=Better_B
/CRITERIA=CI(.95).
We will focus on the heterogeneous variance *t*-test.
