Results for ‘thermometer’-study
| Actual a | ‘Significant’ (n = 53) | ‘Non-significant’ (n = 73) | (z-value) p-value | Effect size | |
|---|---|---|---|---|---|
| N | 33 | 76 | 50 | (z =-1.75) p = .08 | r = -.15 |
| M group1 | 5.12 | 2.70 | 3.50 | ||
| M group2 | 4.13 | 4.05 | 4.00 | ||
| Mdiff | 0.99 | 2.00 | 1.00 | (z =-5.27) p < .001 | r = -.47 |
| SD group1 | 1.22 | 1.00 | 1.25 | ||
| SD group2 | 1.41 | 8.00 | 10.00 | ||
| Cohen’s d | 0.78b | 0.60 | 0.30 | (z =-3.88) p < .001 | r = -.34 |
Note. aThe actual study reported a significant effect. Attempts to replicate the effect of temperature on social relations within the Many Labs Replication Project have failed, however [54].
bCohen’s d = .78 is reported in the paper. Calculating effect size from means and standard deviations using the Campbell effect size calculator available at http://www.campbellcollaboration.org/resources/effect_size_input.php results in d = .75, 95% C.I = [0.05; 1.46].
