outcome (increased class participation). Validity is in four types and these are: Conclusion‚ Construct‚ Internal and external validity. Conclusion validity tries to find out the relationship between a program and the observed outcome. For instance‚ a connection between Re-entry policy and increased failure rate in schools. Construct validity looks at the extent to which a test measures what it claims or intend to measure. Internal validity refers to how well an experiment has been done and the extent

Challenges to validity and reliability In the based that the research question where answer by the survey show that there was a validity and reliability upon it. The challenges to gain the validity through out the entire research were less. The research question has to be reworded to gain the specific answers the research need from the sample.

Reliability | Application and APPROPRIATENESS | Strengths | Weaknesses | Internal Consistency | This measure of reliability is appropriate when trying to determine the difference in reliability from shortening or lengthening a test (Cohen & Swerdlik‚ 2010). Here I am specifically referring to the Spearman-Brown formula being used to determine internal consistency. A researcher could also use other measures of internal consistency meant for heterogeneous test items‚ such as Inter-item consistency
