Proposed Research Question: I want to know if number of hours study per week has effect on the academic achievement of urban adolescent student. Alternative hypothesis: The factor number of hours study per week has effect on the academic achievement of urban adolescent student. Null hypothesis: The factor number of hours study per week has no effect on the academic achievement of urban adolescent student. Independent factors – Study hours Dependant variables – Urban adolescent student
Comparing One Group (a sample) to a Population (Argosy, 2009) Is the academic achievement of urban adolescent student is different from 70%? Is the academic achievement of urban adolescent student is greater than 70%? (Directional) Is the academic achievement of urban adolescent student is less than 70%? (Directional) Using the single –sample t-test Comparing Two Unique Groups (Argosy, 2009) Is the academic achievement of urban adolescent student studying more than 10 hours is different from student studying less than 10 hours?
Is the academic achievement of urban adolescent student studying more than 10 hours is better from student studying less than 10 hours? (Directional) Is the academic achievement of urban adolescent student studying more than 10 hours is worse from student studying less than 10 hours? (Directional) Using the independent Sample t Comparing One Group at Two Points in Time (Argosy, 2009) The effect of audio/visual teaching on the academic achievement of urban adolescent student
Is the performance is different from no audio/visual aid teaching? Is performance improved with audio/visual aid teaching? (Directional) Is performance decreased with audio/visual aid teaching? (Directional) Comparing a “pair” of scores -Dependent sample t-test 3 References Argosy University Online (January, 2009). E7031. Methods and Analysis of Quantitative Research.
