# Statistics

Learn and practice identifying statistical questions, measuring variability and making predictions from sample data with interactive resources from GeoGebra.

## Middle School

### Comparing Data Distributions

Compare data and distributions of data, numerical and contextual, to draw conclusions, considering the measures of center and measures of variability.

### Identifying Statistical Questions

Recognize that a statistical question is one that will require gathering data that has variability.

### Inferences From Samples

Make inferences about a population based on a sample and compare variation in multiple samples.

### Linear and Nonlinear Relationships in Data Sets

Identify linear and nonlinear relationships in data sets.

### Measures of Variability

Select the appropriate measure of variability; choose a measure of variability based on the presence of outliers, clusters, and the shape of the data distribution.

### Observation, Measurement, and Sampling

Describe a data set by its number of observations, what is being measured, and the units of measurement.

### Population vs. Sample

Distinguish between a population and a sample and draw conclusions about the sample (random or biased).

### Predictions From Samples

Make predictions based on results from surveys and samples.

### Quartiles and Interquartile Range of Data

Determine the quartiles or interquartile range for a set of data.

### Range of Data Sets

Describe data using the range.

### Set Theory

Use set notation to describe domains, ranges, intersection, and union of sets. Identify cardinality of sets, equivalent sets, disjoint sets, complement, or subsets.

### Two-way tables

Construct and interpret a two-way table to display two categories of data from the same source.
