- OGM.13.STA.1Represent and interpret single-variable data using dot plots, box plots, and histograms (where area represents frequency); compute and interpret measures of center (mean, median), position (percentiles, quartiles), and dispersion (IQR, variance, standard deviation) from raw and summary statistics.
- OGM.13.STA.2Identify, analyze, and handle outliers and anomalies in datasets; clean data with missing values, and evaluate the effect of extreme values on distribution shape, center, spread, and presentation choices.
- OGM.13.STA.3Fit empirical data to a continuous Normal distribution $N(\mu, \sigma^2)$; use calculators, software, and standard normal $Z$-tables to estimate probabilities, percentiles, and population proportions, identifying distribution points of inflection and recognizing when normality assumptions fail.
- OGM.13.STA.4Summarize bivariate categorical data in two-way frequency tables; compute joint, marginal, and conditional relative frequencies; evaluate associations, trends, and independence between categorical variables.
- OGM.13.STA.5Represent quantitative bivariate data on scatter plots; fit linear, quadratic, and exponential models; compute and interpret Pearson's correlation coefficient $r$, slope, and intercept; assess model adequacy using residual plots; and rigorously distinguish correlation from causation.
