q2 i? T-calculated values were below the critical value, so the null hypothesis could not be rejected on pre-test scores. → Bahadur 2013

Evidence¶

Bahadur 2013¶

Bahadur, G. K. & Oogarah, D. (2013). Interactive whiteboard for primary schools in Mauritius: An effective tool or just another trend? IJEDICT, 9(1), 19-35. http://ijedict.dec.uwi.edu//viewarticle.php?id=1559

q2 · i? · causal · r1

Analysis of the 10-question pre-test across classes 1A, 1B and 2C (Table 4), comparing groups before lessons; the article reports T-calculated values of -0.137, 0.330 and 0.56 against a critical value of 2.262.

"The critical T-value (2.262) is greater than the T- calculated values which are -0.137, 0.330 and 0.56 respectively; thus the null hypotheses cannot be rejected. We can then conclude that there is no difference in the scores obtained by the students for each question."
