# High School: Statistics & Probability: Interpreting Categorical and Quantitative Data

### HSS.ID.A.1

Represent data with plots on the real number line (dot plots, histograms, and box plots).

### HSS.ID.A.2

Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

### HSS.ID.A.3

Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).

### HSS.ID.A.4

Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

### HSS.ID.B.5

Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.

#### HSS.ID.B.6.a

Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.

#### HSS.ID.B.6.b

Informally assess the fit of a function by plotting and analyzing residuals.

#### HSS.ID.B.6.c

Fit a linear function for a scatter plot that suggests a linear association.

### HSS.ID.C.7

Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.

### HSS.ID.C.8

Compute (using technology) and interpret the correlation coefficient of a linear fit.

### HSS.ID.C.9

Distinguish between correlation and causation.
