PSYB01H3 Lecture Notes - Lecture 6: Simple Random Sample, Quota Sampling, Multimodal Distribution
Document Summary
Nonprobability sampling (this is everything that we do in psych) (not everyone has an equal chance of participating: convenience sampling. Choosing groups that are easier to study ie. ppl who agree & say (cid:498)yes(cid:499) to participate in study. How you get the group of ppl is v arbitrary; you go out and find: quota sampling. Selecting a group of subjects (sample) from a larger population. 1st years from uni: stratified random sampling. Probability sampling (everyone has an equal chance of being selected) Random sample in regions, then random district of schools, then random selection of schools, then random sample of classes ect since you are making inferences from a small group to a large group, you can. Number of participants who receive each possible score. Proportion of ppl that scored on each item: (graph of freq: histogram) X axis possible scores on assessment (1-10)
