Unit 7 Key Concepts and Skills
Topic	Data Analysis Skills
Data, Describing Data, and Central Tendency
Data	Differentiate between data, information and a collection of numbers.
Mean	Identify/calculate the mean of a data collection numerically or graphically; compare the mean of multiple data collections.
Median	Identify the mean of a data collection numerically or graphically; compare the median of multiple data collections.
Mode	Identify the mode of a data collection numerically or graphically; compare the modes of multiple data collections.
Range	Calculate the range of a data collection; compare the range of multiple data collections.
Quartiles	Identify the first, second, and third quartile of a data collection; compare quartiles of multiple data collections.
Min	Order data, identify the minimum values of a data collection.
Max	Order data, identify the maximum values of a data collection.
Inter Quartile Range	Calculate the interquartile range of a data collection; compare the interquartile range of multiple data collections.
Outliers	Identify outliers or candidates from a data collection.
Displaying Data
Stem and Leaf plots	Create a stem-and-leaf plot from a data collection. Read and interpret a stem-and-leaf plot
Tables and Charts	Collect, organize, and /represent data in a table or chart. Read and interpret a table or chart
Bar Graphs	Create a bar graph from a data collection. Read and interpret a bar graph
Double Bar Graphs	Create a double bar graph from multiple data collections. Read and interpret a double bar graph
