Understanding the Importance of Frequency Tables
When it comes to creating a histogram, selecting the correct frequency table is crucial. A frequency table is a table that displays the number of times each value in a dataset occurs. In this article, we will discuss how to select the correct frequency table for a histogram, using the given data as an example.
What is a Frequency Table?
A frequency table is a table that displays the number of times each value in a dataset occurs. It is a useful tool for understanding the distribution of data and identifying patterns. Frequency tables can be used to create histograms, which are graphical representations of data that show the distribution of values.
Types of Frequency Tables
There are two main types of frequency tables: univariate and bivariate. A univariate frequency table displays the number of times each value in a single variable occurs. A bivariate frequency table displays the number of times each value in two variables occurs.
Selecting the Correct Frequency Table
To select the correct frequency table, we need to consider the type of data and the type of analysis we want to perform. In this case, we are given a dataset of exam scores and we want to create a histogram to understand the distribution of scores.
Univariate Frequency Table
A univariate frequency table is the most common type of frequency table. It displays the number of times each value in a single variable occurs. To create a univariate frequency table, we need to count the number of times each value in the dataset occurs.
Creating a Univariate Frequency Table
To create a univariate frequency table, we can use the following steps:
- Count the number of times each value in the dataset occurs.
- Create a table with the values in the dataset as the rows and the frequency of each value as the columns.
- Sort the table in descending order of frequency.
Example: Creating a Univariate Frequency Table
Let's create a univariate frequency table for the given dataset:
Value | Frequency |
---|---|
62 | 1 |
64 | 1 |
65 | 1 |
66 | 1 |
67 | 1 |
68 | 1 |
69 | 2 |
81 | 1 |
82 | 2 |
83 | 3 |
86 | 1 |
88 | 2 |
89 | 1 |
93 | 1 |
94 | 1 |
Bivariate Frequency Table
A bivariate frequency table displays the number of times each value in two variables occurs. To create a bivariate frequency table, we need to count the number of times each value in the two variables occurs.
Creating a Bivariate Frequency Table
To create a bivariate frequency table, we can use the following steps:
- Count the number of times each value in the two variables occurs.
- Create a table with the values in the two variables as the rows and the frequency of each value as the columns.
- Sort the table in descending order of frequency.
Example: Creating a Bivariate Frequency Table
Let's create a bivariate frequency table for the given dataset:
Value 1 | Value 2 | Frequency |
---|---|---|
62 | 65 | 1 |
64 | 66 | 1 |
65 | 67 | 1 |
66 | 68 | 1 |
67 | 69 | 1 |

Conclusion
In conclusion, selecting the correct frequency table for a histogram is crucial. A univariate frequency table displays the number of times each value in a single variable occurs, while a bivariate frequency table displays the number of times each value in two variables occurs. To create a univariate frequency table, we need to count the number of times each value in the dataset occurs. To create a bivariate frequency table, we need to count the number of times each value in the two variables occurs. By selecting the correct frequency table, we can create a histogram that accurately represents the distribution of data.
