This study examined the reliability and difficult indices of
Multiple Choice (MC) and True or False (TF) types of
objective test items in a Mathematics Achievement Test
(MAT). The instruments used were two variants- 50-items
Mathematics achievement test based on the multiple choice
and true or false test formats. A total of five hundred
(500) students randomly selected from ten senior secondary
schools in five Local Government Areas of Akure, Ondo State
served as sample for the study. The results of the null
hypotheses tested at p=0.05 showed that there was no
significant difference between the reliability coefficients
of MC and TF test items. Also, there was no significant
difference between the difficult indices of MC and TF test
items. Hence, it was recommended that a combination of both
MC and TF types of tests should be used to evaluate
students’ achievement in schools.
Key words:
Reliability indices and Coefficients, difficulty indices,
achievement tests, multiple choice, true false tests. |
