Question

An electronics store is determining which size monitors have the highest sales rate. So, they record the size (in inches) of each monitor sold in a given day. These size are given below. Construct a frequency table for these values using 4 classes. 13.6,13.6,32.5,29.7,29.9,15.5,13.5,21.1,22.2,26.9,29.6,13.3,30.8,31.1

Answer 1

The frequency table for the monitor sizes using 4 classes where the most popular monitor sizes are in the 13.3-18.1 inch and 27.7-32.5 inch ranges.

What is a Frequency Distribution Table?

A frequency distribution table displays the frequency of each data set in an organized way. It helps us to find patterns in the data and also enables us to analyze the data using measures of central tendency and variance. The first step that a mathematician does with the collected data is to organize it in the form of a frequency distribution table. All the calculations and statistical tests and analyses come later.

Class Frequency

13.3-18.1 5

18.1-22.9 2

22.9-27.7 1

27.7-32.5 5

As you can see, the most popular monitor sizes are in the 13.3-18.1 inch and 27.7-32.5 inch ranges.
