This AP Psychology study guide covers descriptive statistics, focusing on summarizing data with measures of central tendency (mean, median, mode) and variation (standard deviation, range). It explores correlation (positive, negative, and no correlation) and emphasizes the distinction between correlation and causation. The guide also discusses frequency distributions (normal, bimodal, positively/negatively skewed) and highlights the 68% and 95% rules for normal distributions. Finally, it touches on statistical significance.
