Homework Answers
Ans. Analyze the terms validity and reliability
Validity - validity refers to the degree to which an instrument measures what it is supposed to be measuring
Reliability - reliability is the ability of the tool to create reproducible results .
Meaning in quantitative research - in quantitative research, the variables are measured and quantified where as in qualitative research the variables are not quantified.
Examples of validity and reliability
-internal validity - the extent to which it can be inferred that the independent variable caused or influenced the dependent variable
- External validity - the generalizability of the observed relationships across sample , setting , or time
- construct vslidity - the degree to which key constructs are adequately captured in the study
Example of reliability
- test retest reliability - it refers to the degree to which test results are consistent over time.
