Objective
By the end of this lesson, you will be able to use quartiles and box plots to compare sets of data and evaluate sources of data.
Materials and Prep
- Paper
- Pencil
- Calculator (optional)
- Basic understanding of data sets and measures of central tendency
Activities
Create two sets of data related to a topic you're interested in. Calculate the quartiles for each set and draw box plots to compare them.
Research online sources of data on a topic you find intriguing. Evaluate the reliability of the data by looking for any biases or inconsistencies.
Ask a family member or friend for a set of data they find interesting. Calculate the quartiles and create a box plot to represent the data visually.
Talking Points
"Quartiles divide a data set into four equal parts. They help us understand the spread and distribution of the data."
"Box plots provide a visual representation of the five-number summary of a data set, including the minimum, maximum, median, and quartiles."
"When evaluating sources of data, it's important to consider the credibility of the source, the methodology used to collect the data, and any potential biases."
"By comparing box plots of different data sets, we can quickly identify variations in the spread and central tendencies of the data."
