Subclaims¶

q3 i? The distribution of dropout odds ratios showed significant between-study heterogeneity (Q=238.6; I2 = 45.9%), motivating meta-regression analysis of study characteristics. → Wilson 2011

Evidence¶

Wilson, S. J., Tanner-Smith, E., & Lipsey, M. W. (2011). Dropout Prevention and Intervention Programs: Effects on School Completion and Dropout Among School-aged Children and Youth. 2011 SREE Conference. http://ies.ed.gov/ncee/wwc/reports/dropout/topic/#top doi:10.4073/csr.2011.8

q3 · i? · quant-synthesis · r2

Heterogeneity test in the random-effects synthesis of the 130 coded samples. The article reports "significant heterogeneity (Q=238.6*; I2 = 45.9%)", indicating between-study differences beyond subject-level sampling error, which prompted a random-effects meta-regression.

"The distribution of dropout odds ratios evidenced significant heterogeneity (Q=238.6*; I2 = 45.9%). That is, there are between-study differences in effect sizes that are greater than would be expected from the subject-level sampling error."
