# Q3, W1: January 26th – 29th Advanced Math

Teacher Felicia Taylor Advanced Math 7th 19 Focus 5: Statistics
Standard(s) Taught

#### Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions.

Learning Targets and Learning Criteria

Students are successful when they can…

• critique examples of random sampling as statistical tools using precise mathematical vocabulary:  random sampling, population, and valid generalizations.
• design random samplings to collect the data given statistical questions. Defend the samplings as random.
• construct a scatter plot by plotting ordered pairs on a coordinate grid representing the relationship between two data sets.
• describe patterns in the plotted points such as clustering, outliers, positive or negative association, and linear or nonlinear association and describe the pattern in the context of the measurement data.
• explain the patterns of association of scatter plots of bivariate data in the context of the data sample.
• draw valid inferences and generalizations from random samplings of populations and justify their inferences and generalizations as valid using appropriate vocabulary.
• explain the variability in multiple random samples and gauge how far off an estimate may be.
