In this case stratified sampling would be a good method to use in my point of view because it is representative of both studious pupils and poorer achieving ones. Definition what is simple random sampling Simple random sampling selects a smaller group (the sample) from a larger group of the total number of participants (the population). Learn how it works in our ultimate guide. She then asks 5 of each group at random and sends up asking 25. Simple random sampling is the sampling method that makes this easy. Stratified sampling- she puts 50 into categories: high achieving smart kids, decently achieving kids, mediumly achieving kids, lower poorer achieving kids and clueless class-skippers. The simple random sample is a type of sampling where the sample is chosen on a random basis and not on a systematic pattern. Cluster sampling- she puts 50 into random groups of 5 so we get 10 groups then randomly selects 5 of them and interviews everyone in those groups -> 25 people are askedĢ. She wants to know whether most people like homework or not.ġ. Mia has a population of 50 pupils in her class.
Every possible sample of a given size has the same chance of. Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample. Cluster samples put the population into groups, and then selects the groups at random and asks EVERYONE in the selected groups.Ī stratified random sample puts the population into groups (eg categories, like freshman, sophomore, junior, senior) and then only a few (people for example) are selected from each sample. Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population).
