PSYC1011 Lecture Notes - Lecture 4: Statistical Inference, Descriptive Statistics, Confounding
Document Summary
Giving protein to young girls and boys. Confounding variables could have affected the results, cant infer causation. In an experiment you have to isolate the variable you want to study in order to reach a viable conclusion. Placebo effect type citation could be at play: while one group got protein and the other didn"t, one group also got a pill and the other didn"t. Be careful of the average could be mean or median. Descriptive statistics: what we use to describe data. Help us to estimate how likely our results are not due to chance. The greater the n, the more the se, and the less, v -> the more likely it is to be statistically significantly. Graph going up, positive correlation, as one goes up the other goes up. Graph goes down, negative correlation, as one goes down the other goes down.
