Calculating the Missing Relative Frequency

Oct 13, 2025 by wbrum.org 32 views

Introduction

In statistics, relative frequency is a measure of the proportion of times a particular value or category occurs in a dataset. It is calculated by dividing the frequency of a value or category by the total number of observations in the dataset. In this article, we will explore how to calculate the missing relative frequency from a given table.

Understanding the Table

The table below shows the number of responses, frequency, and relative frequency for a particular dataset.

Number of Responses	Frequency	Relative Frequency
0	4	0.2
1	10	0.1
2	4	0.2
3	2	0.1

Calculating the Missing Relative Frequency

To calculate the missing relative frequency, we need to first calculate the total number of observations in the dataset. This can be done by adding up the frequencies of all the values or categories.

Total number of observations = 4 + 10 + 4 + 2 = 20

Next, we need to calculate the missing relative frequency. Since the table already shows the relative frequencies for the values 0, 1, 2, and 3, we can calculate the missing relative frequency by subtracting the sum of the given relative frequencies from 1.

Sum of given relative frequencies = 0.2 + 0.1 + 0.2 + 0.1 = 0.6

Missing relative frequency = 1 - 0.6 = 0.4

Interpretation of the Results

The missing relative frequency represents the proportion of times a value or category occurs in the dataset that is not accounted for by the given values or categories. In this case, the missing relative frequency is 0.4, which means that 40% of the observations in the dataset are not accounted for by the values 0, 1, 2, and 3.

Conclusion

In conclusion, the missing relative frequency from the table below is 0.4. This represents the proportion of times a value or category occurs in the dataset that is not accounted for by the given values or categories.

Calculating the Missing Relative Frequency: Step-by-Step

Step 1: Calculate the Total Number of Observations

To calculate the total number of observations, we need to add up the frequencies of all the values or categories.

Total number of observations = 4 + 10 + 4 + 2 = 20

Step 2: Calculate the Sum of the Given Relative Frequencies

To calculate the sum of the given relative frequencies, we need to add up the relative frequencies of the values 0, 1, 2, and 3.

Sum of given relative frequencies = 0.2 + 0.1 + 0.2 + 0.1 = 0.6

Step 3: Calculate the Missing Relative Frequency

To calculate the missing relative frequency, we need to subtract the sum of the given relative frequencies from 1.

Missing relative frequency = 1 - 0.6 = 0.4

Step 4: Interpret the Results

The missing relative frequency represents the proportion of times a value or category occurs in the dataset that is not accounted for by the given values or categories.

Example Use Case

The missing relative frequency can be used in a variety of applications, such as:

Data analysis: The missing relative frequency can be used to identify patterns or trends in the data that are not accounted for by the given values or categories.
Hypothesis testing: The missing relative frequency can be used to test hypotheses about the distribution of the data.
Predictive modeling: The missing relative frequency can be used to build predictive models that take into account the missing values or categories.
