TopIf we have two values i.e. actual value and total number of values then we can find the relative frequency of two values by finding the Ratio of the actual number to the total number.
For example: If you select 10 hospitals out of 50 hospitals then firstly we find the frequency of given data and then with the help of frequency data we find the relative frequency:
Then the frequency of hospitals is 10; by using the definition of relative frequency we get:
So the relative frequency of hospitals is 10/50 because we know that it is the ratio of actual number to the total number of values.
Now we will see how to how to create a relative Frequency Histogram.
We have to follow some steps for creating or constructing the histogram.
Step1: First we take some data values for making the histogram.
Step2: When we plot a graph, then we take independent variable along the horizontal axis and the dependent variable along the vertical axis.
By using these steps we can draw any histogram. Now we find the relative frequency of some data.
Suppose we are looking at the collection of anything and if we have 13 observations:
Home, car, hospitals, school, home, hospitals, home, colleges, car, school, colleges, school, home then we find the relative frequency?
For finding the relative frequency of an object we have to follow all the above steps:
Step1: Firstly take any number.
Step2: Then we find the frequency of the given collection or data.
So the frequency of home is: 4;
The frequency of car is: 2;
The frequency of hospitals is: 2;
The frequency of school is: 3;
The frequency of colleges is: 2;
And by using the above data we can find relative frequency we can easily find the relative frequency:
So the relative frequency of home is: 4 / 13;
The relative frequency of car is: 2 / 13;
The relative frequency of hospitals is: 2 /13;
The relative frequency of school is: 3 /13;
The relative frequency of colleges is: 2 /13;
This is how we find relative frequency.
