Document Summary
Research methods: general strategies for conducting scientific studies. (the population is: example) > you need to narrow down the population and turn it into an average sample. The entire population is far too large to research in its entirety. > very important in research, where findings are published. 80% of articles submitted do not get published. >each member in the population has an equal chance of being included in the sample. It is hard to get a random sample. Biased locations for conducting these samples are often avoided. Each member in the sample has an equal chance of being assigned to the experimental condition or control condition. Participants are not allowed to choose which group they will be in because of influential factors. >manipulate one variable under carefully controlled conditions so the changes in the other variable can be observed. > this allows us to determine cause and effect. Independent variable (iv)= variable that is directly manipulated by the experimenter.
