Document Summary
Descriptive stats - describe data without generalizations (ex mean, median, mode, Inferential stats - draw conclusion of some unknown aspect of a population. Null hypothesis - observation occurs at same frequency as random variance or by chance. Use convention of 5% (2 sd away from mean) for every 1/20 experiments, there is a possibility that the results are due to chance. P < 0. 05 observed data is statistically different from expected data. Type 1 - no difference between variance and collected data. Type 2 - there is a difference between variance and collected data, but it wasn"t present in data. Aggregation - multiple isopods gathering in a certain area. Thermoreaction - different activity depending on temperature. For 30s, note which side the isopod spends most of its time in. Place one in the chamber release site: start timer when isopod starts moving and observe the number of squares the isopod moves in a certain amount of time.
