Describe the mean and median of heights of your class. You can visualise the heights on a dot plot.
Step 1: Collect height data from your classmates.
Step 2: Create a dot plot showing the distribution of heights.
Step 3: Calculate the mean (sum of heights divided by number of students).
Step 4: Find the median (middle value when heights are sorted).
Step 5: Describe whether the mean and median are close together or far apart.
Step 6: Identify any outliers that might affect the mean.
Explanation
This activity requires students to apply concepts of mean, median, and dot plots to real data from their own class. They should observe the shape of the distribution, note any clustering or spread, and compare the mean and median values.
