7582679447	descriptive statistic	numerically measures and describes characteristics of a group	0
7582679448	measure of central tendency	a single score that represents a whole set of scores; summarizes data	1
7582679449	mode	the frequency that occurs the most	2
7582679450	mean	the average of the scores	3
7582679451	median	the middle score	4
7582679452	skewed distribution	a representation of the scores that lack symmetry around average value	5
7582679453	range	the difference b/t the highest and lowest scores	6
7582679454	standard deviation	measures how score deviate from one another; makes the mean meaningful	7
7582679455	normal curve	symmetrical, bell shaped curve that describes distribution of many types of data	8
7582679456	inferential data	numerical data that allows one to generalize	9
7582679457	statistical significance	statistical statement of how likely it is that an obtained result occurred by chance	10
7582679458	what does it mean when something is statistically significant?	it means that the results did not occur by chance	11
7582679459	name research methods that generate descriptive statistics	case studies, natural observation, survey w/o random sampling	12
7582679460	name research methods that generate inferential statistics	experiments, surveys with random sampling	13
7582679461	small statistical deviation	scores are closer together	14
7582679462	large statistical deviation	scores are further apart	15
