| What would your hypothesis look like if you had an experiment? | show 🗑
|
||||
| show | Tests the effect of one independent variable for each level of another independent variable to determine how the IVs interact to effect the dependent variable. Compares the differences of the levels of one IV across the levels of another IV.
🗑
|
||||
| show | Each member of the population has an equal probability of being selected using random sampling. E.g. student are chosen randomly from list of all student at a university
🗑

🗑
|
||||
| show | Easier to obtain than probability samples
🗑
|
||||
| show | May not represent the population well due to selection bias because random sampling is not used
🗑
|
||||
| What is a quota sampling technique? | show 🗑
|

| Example of quota sampling | show 🗑
|

| Pros of quota sampling | show 🗑
