Use random sampling to draw inferences about a population.

• Create a Graph
This applet allows students to create bar, line, area, pie, and XY graphs.
• Estimating: Counting Trees
This lesson unit is intended to help educators assess how well students are able to solve simple problems involving ratio and direct proportion, choose an appropriate sampling method, and collect discrete data and record them using a frequency table.
• Food for Thought
This graphing activity allows students to create and analyze two- and three-dimensional graphs.
• Marbles
This activity helps the student understand randomness and probability by pulling marbles out of a bag.
• Statistics and Probability - Standards 1, 2, 3 and 4 Curriculum Guide
The Utah State Office of Education (USOE) and educators around the state of Utah developed these guides for Mathematics Grade 7 Cluster "Use Random Sampling to Draw Inferences About a Population" / Standards 1, 2, 3 and 4.
• Storage Shed - student task
Students are going to build storage sheds as a fund raising project, but before they can start they must determine the best dimensions for the shed, make scale drawings and decide on how much to charge for each shed.
In this task, students analyze a survey to decide how many candy bars students typically eat in a week.
In this task, students must estimate the number of trees on a tree farm - without counting every tree.
