1)What is meant by reliability and validity?
2) What are the different research designs?
3) What are the common threats to validity?​

Sagot :

Answer:

1.Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

2.There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause- effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.

3.There are eight threats to internal validity: history, maturation, instrumentation, testing, selection bias, regression to the mean, social interaction and attrition.

Answer:

1.) Reliability is about the consistency of a measure, and validity is about the accuracy of a measure

2.) Data collection, measurement, and analysis

3.) History, maturation, selection, mortality and interaction of selection and the experimental variable are all threats to the internal validity of this design
