There are so many questions to be answered. To examine the world around us, we need a method, an organization scheme. This lesson focuses upon Tally Sheets, Stem and Leaf Plots, Spreadsheets, and making decisions upon which representation is most appropriate.

Represent data with plots on the real number line (dot plots, histograms, and box plots).

Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.

Fit a function to the data; use functions fitted to data to solve problems in the context of the data.

Fit a linear function for a scatter plot that suggests a linear association.

Construct and interpret two-way frequency tables of data when two categories are associated with each object being classified. Use the two-way table as a sample space to decide if events are independent and to approximate conditional probabilities.

summarize a data set with multiple categories using a frequency table, dot plot, pictograph, or bar graph with scaled intervals; and

represent categorical data with bar graphs or frequency tables and numerical data, including data sets of measurements in fractions or decimals, with dot plots or stem-and-leaf plots;

represent discrete paired data on a scatterplot; and
