Content spans the full behavioral statistics curriculum: introduction to statistics (population vs. sample, parameter vs. statistic, descriptive vs. inferential statistics, random sampling, scales of measurement including nominal/ordinal/interval/ratio), frequency distributions (frequency distribution tables, grouped frequency distributions, frequency distribution graphs, percentiles and percentile ranks), central tendency (mean, median, mode), variability (range, standard deviation, variance), z-scores (location of scores and standardized distributions), probability, probability and samples (distribution of sample means), introduction to hypothesis testing (null hypothesis, alpha level, Type I and Type II errors), introduction to the t statistic, t test for two independent samples, t test for two related samples, introduction to analysis of variance (ANOVA), two-factor analysis of variance, correlation and regression, and the chi-square statistic (tests for goodness of fit and independence) . Sample questions cover topics such as positive vs. negative skew (positive skew has tail extending to the right; scores with highest frequencies are on the left side of the distribution), descriptive statistics (organizing and summarizing data), inferential statistics (making conclusions about populations based on samples), and correlation coefficient interpretation (+1.00 indicates perfect positive relationship) .
