Results From the Multilevel Model Using Lab Mates’ Prosocial-Affordance Beliefs (PABs) Regarding Science to Predict Interest in a Science Career: Random Effects
| Random effect | Standard deviation | Variance component | χ2 | p |
|---|---|---|---|---|
| Base interest in science career, U0j | 0.83 | 0.68 | χ2(6) = 26.52 | < .001 |
| Individual-level PABs regarding science, U1j | 0.19 | 0.04 | χ2(7) = 5.23 | > .500 |
| White, U2j | 1.10 | 1.22 | χ2(6) = 19.71 | .003 |
| Asian, U3j | 1.99 | 3.96 | χ2(6) = 34.80 | < .001 |
| Experience of interest in research, U4j | 0.53 | 0.28 | χ2(7) = 8.12 | .321 |
| Level 1 effect, εij | 1.23 | 1.50 | — | — |
Note: Ethnicity was dummy-coded (0 = underrepresented-minority student, and 1 = White or Asian, depending on the variable).
