1.1 Recording the data using appropriate instruments:
- Use a pen and paper to jot down the age of each classmate
- Use a calculator to perform any necessary calculations
- Use a tally sheet to keep track of the number of classmates in each age group
1.2 Classifying and organizing the data:
- Create categories or class intervals for the ages (e.g. 10-12, 13-15, 16-18, etc.)
- Use tallies to count the number of classmates in each age group
- Create a frequency table to display the data in an organized manner
1.3 Calculating and analyzing measures of central tendency and spread:
- Calculate the mean, median, and mode of the data to determine central tendency
- Calculate the range and standard deviation to analyze the spread of the data
- Analyze the results to understand the distribution of ages among classmates
1.4 Representing the data using appropriate graphs:
- Create a bar graph or histogram to visually represent the frequency of each age group
- Use a box plot to show the spread of ages and identify any outliers
- Present the data in a clear and concise manner for easy interpretation by others.
