Students use their understanding of projectile physics and fluid dynamics to find the water pressure in water guns. By measuring the range of the water jets, they are able to calculate the theoretical pressure. Students create graphs to analyze how the predicted pressure relates to the number of times they pump the water gun before shooting.

Students get their first experience of statistics in this unit, defining a statistical question and investigating the key concepts of measures of center and measures of variability.

Students investigate how to use sampling to make inferences about larger populations of interest, engaging in hands-on activities to select random samples and to compare samples of different sizes.

This 2-minute video lesson shows how to find the range and the mid-range of a set of numbers. [Statistics playlist: Lesson 2 of 85]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

Download these free worksheets to sharpen your skills with statistics and probability. Sheets focus on collecting and organizing data, measures of central tendency (mean, median, mode, and range), and probability.

The domain of a function is all the possible values of x's of ordered pairs; whereas the range of a function is all the possible values of y's of ordered pairs. You can easily find them by graphing the functions or ordered pairs. Let's see how in this lesson. Includes a video tutorial, examples, and practice problems.

The results of researches are heavily affected by the process of data collection. However, the process is prone to errors. For example, biased and misleading survey questions, and leading survey questions can all affect the results greatly. In this video, you will learn how to identify and fix these errors. [2:31]

Slope intercept form is one of the three forms we can use to express a straight line. It is a linear function too; meaning the function can tell you its domain and range. Watch this video tutorial for a full explanation along with examples. [19:10]

Site contains information on the statistical term standard deviation. It gives a definition and shows how to calculate it. It has a link to information on the absolute value of a deviation and how the topics are related.

The CyberSquad searches for HackerŒë_í_Œ_ castle based on a survey of where town residents have last seen him in this video from Cyberchase.

Find a quick, concise explanation of domain and range. Several examples are given and clearly explained.

The interquartile range is the middle 50% of a data set. Watch this tutorial to learn how to dissect data and understand this concept. [4:33]

The range of a relation is the set of the second coordinates from the ordered pairs. This tutorial explains the range of a relation. [6:59]
