Subclaims¶

q2 i? Willis' lambda analyses indicated significant multivariate differences between the three groups on both the post-test (lambda=0.91; f=2.27) and the postponed test (lambda=0.91; f=2.32). → Al-Balushi 2018

q2 · i? · causal · r2

Omnibus MANCOVA (Willis' lambda) on the postponed administration of the science achievement test across the mental, technological and control groups; the post-test omnibus was also significant (lambda=0.91; f=2.27).

"Willis’ lambda analysis for the postponed test detected statistically significant differences (la mbda=0.91; f=2.32)."
