Math Example--Measures of Central Tendency--Mode: Example 63

Topic

Measures of Central Tendency

Description

This example showcases a situation of measures of central tendency, where the goal is to identify a key summary measure in a set of data. The image shows Example 63 with a list of numbers. After sorting them in ascending order, it identifies two modes: "20" and "44." This demonstrates that a data set can have multiple modes, which occurs when two or more numbers appear with the highest frequency.

Measures of Central Tendency lessons are instrumental in providing students with a better understanding of how to interpret data through these examples. Each example highlights distinct scenarios which reinforce the concept of determining frequency of occurrences within given sets, enhancing students' analytical skills.

Seeing multiple worked-out examples is crucial in solidifying a student's grasp on a concept. Each example contributes unique perspectives and challenges that can arise when thinking about data sets. This varied approach not only caters to diverse learning styles but also ensures that all students can see the relevance of these concepts in their learning journey.

Teacher's Script

In this example, we're presented with the following set of numbers: 44, 41, 20, -1, 31, 25, 0, 30, 33, 44, 34, 19, 32, 12, 10, 20, 1, and 28. Our task is to find the mode. Remember, the mode is the value that appears most frequently in a data set. Let's start by arranging these numbers from least to greatest. Now, look carefully at our sorted list. Do you notice any numbers that appear more than once? Excellent observation! Both 20 and 44 appear twice, while all other numbers appear only once. This means our data set has two modes: 20 and 44. This situation is called a bimodal distribution. In real-world data, having two modes could indicate two distinct groups or trends within our data. For example, if these were test scores, it might suggest two common performance levels among students.
