Math: Intro to Statistics - Average, Median, Mode Part 2 (Sample)

Goal:

Sometimes when calculating an average you find that the total number of items you have does not divide evenly into the number of piles that you need. The goal of this activity is to teach the child what to do if you run into this situation.

Pre-requisite:

• Division
• Fractions/Decimals
• How to calculate the average (see Intro to Statistic Part 1)

Description of Activity:

In this follow on video to Intro to Statistics Part 1 Professor Alfie shows us what to do if we run into the situation described above. By splitting each individual stick into the number of people we have we can demonstrate to the child that if our average is not a whole number we need to use fractions (or decimals).

Building on this Activity

Once the child has a basic understanding of what the terms average, median and mode mean you can begin to collect data out in the real world to practice these calculations. The key as always is to make the data collection intrinsically motivating to the child. With Rowan we did it around counting cars on his favorite roads. Think about what your child is interested in and how you can use that interest to collect data with your child. Repeat multiple times so the child has plenty of opportunities to practice their calculations. And let them use a calculator if they need too.
