6th Grade Advanced Math Unit 11

Big Idea:

Find the mean, median, mode, and range for a set of data. Display and interpret data from graphs.

Student Expectations:

Priority TEKS

6.12(C) [Readiness] summarize numeric data with numerical summaries, including the mean and median (measures of center) and the range and interquartile range (IQR) (measures of spread), and use these summaries to describe the center, spread, and shape of the data distribution

6.13(A) [Readiness] interpret numeric data summarized in dot plots, stem-and-leaf plots, histograms, and box plots

7.6(G) solve problems using data represented in bar graphs, dot plots, and circle graphs, including part-to-whole and part-to-part comparisons and equivalents

7.12(A) compare two groups of numeric data using comparative dot plots or box plots by comparing their shapes, centers, and spreads

Focus TEKS

6.12(A) [Supporting] represent numeric data graphically, including dot plots, stem-and-leaf plots, histograms, and box plots

6.12(B) [Supporting] use the graphical representation of numeric data to describe the center, spread, and shape of the data distribution

6.12(D) [Readiness] summarize categorical data with numerical and graphical summaries, including the mode, the percent of values in each category (relative frequency table), and the percent bar graph, and use these summaries to describe the data distribution

6.13(B) [Supporting] distinguish between situations that yield data with and without variability

7.12(B) use data from a random sample to make inferences about a population

Learning Targets:

• Generate the mean, median, mode and range of a data set.
• Describe the central tendency of a data set using the spread and shape of the data
• Create the appropriate graph to display a data set.
• Interpret the data from a given graph
• Compare populations using bar graphs, dot plots, circle graphs, and box-whisker plots.
• Make predictions about a population.

Essential Questions:

• How can you use measures of center to describe data sets?
• How can you summarize and display numeric and categorical data?
• How do we know which type of graph to use when displaying data?
• How can statistics help us make inferences about a population?
