The T Statistic

BackgroundThe decreasing stacks of students in standardized canvass in maths and knowledge check been a cause for concern for close to education reformers hence , intensive restitution had been designed for those who yield been found to perform poorly at these experiments . In to tribulation whether the intervention programs are effective , loads in the introductory proves before the remediation was given will be compared to test scores after the remediationStatement of the problemIs there a evidentiary battle in the test scores of students before and after the remediation program p Independent variableRemediation programDependent variableTest scores (before and after remediationHypothesisNull shot : there is no significant difference in the test scores of students before and after the remediation programAlternative meditation : There is a significant difference in the test scores of students before and after the remediation programEffect sizingThe effect size would signalize the magnitude of the difference of the scores , using Cohen s (1988 ) conventional dust , an effect size of .02 is small .05 is go for and .08 is large . The prospect value would only tell us whether to reject of own the null hypothesis but in no focussing tells us whether the difference is small or largeStatistics t 5 .192df 214n 216Effect size .05ReportThe answered research question is Is there a significant difference between the test scores of students in science and math before and after the remediation program The hypothesis tested is as followsHo :0Ha :? 0The result of the t-test on student scores in the science and math test (t 5 .192 at .

05 ) which is larger than the t-critical value (p 4 .33 with a sample size of 216 and a degrees of freedom of 214 . Therefore the null hypothesis is rejected and the alternative hypothesis is accepted thus , the remediation programs have indeed statistically increased the test scores of the students in science and math . The effect size is at .05 which is moderate (Cohen , 1988 , this would indicate that the difference in the before and after test scores is moderate in value and hence is non really that large as expected . This would mean that the benefaction remediation program has done its work but much(prenominal) is desired before it could be said that it has really reached its objectiveReferencesCohen , J (1988 .
