Performed by stretching open the eyelid and inserting an ice pick into the brain, scraping and destroying the prefrontal lobe. Mean, median, mode: variability/dispersion: how much the data varies range, standard deviation, standard deviation being the average distance of a point from the mean. Inferential statistics: math that shows us whether we can make generalization from our experiments that apply to the larger population: statistical significance: p < 0. 05 chance of the result happening by chance in the real world. Thus, when the result occurs regularly in experimentation, it can be said that it is statistically significant and believable: practical significance: real-world importance. A finding can be statistically significant simply because of a large sample size.
