Big Idea:

### Measures of center are used to interpret univariate data.

1 week

Evidence of Understanding

• use mean, median, and mode to aggregate and interpret univariate data
• describe what is gained and lost by interpreting a data set using the mean, median, or mode
• describe how frequency and range impacts mean, median, and mode
• Interpret statistical representations such as box plots, dot pots, histograms, bar graphs, tables, etc. where some data points occur with a frequency > 1
• describe how removing or adding a value to a data set impacts the mean and median
• explain the effect of an extreme outlier on the mean compared to its effect on the median
• identify which value(s) can be added to the data set that do not alter the median, mean, or mode and justify why

• use range and density to describe how individual data points relate to the mean
• use range and density of points towards the center to describe the variability of a data set
• use standard deviation to describe how range and variation are related to the mean
• use a data set’s distribution to consider and justify where other data points may lie in relation to the mean
• interpret the spread and mean of a statistical distribution.

• interpret and describe connections between the frequency and distribution across different representations (graphs, tables, or charts)
• Determine the extent to which the difference matters
• Articulate the relationship between a normal distribution (a result of a continuous random variable) and a binomial distribution (a result of a discrete random variable).
• Compare the experimental and theoretical probability of a sample space using areas in the distribution curve
