explain how psychologists minimise biases in their explanation of behavior experienced in varios studies ?
Answers
Answer:
Sampling bias is when the sample in question is not representative of the general population.
Selection bias occurs when the participants in the sample are not equally and fairly selected for both the experimental and control groups; this renders any results from the experiment meaningless.
Response bias is when only highly motivated people return a survey. When this occurs, the resulting data is biased toward those with the motivation to answer and submit the survey, and is therefore not representative of the population as a whole.
External validity is the ability to apply conclusions gathered from the results of an experiment to the general population.
Data sets with little variability have values that are similar to each other; data sets with high variability have values that are more spread out.
