how to find the missing frequency among other frequencies of histogram if the range i given.

Sure, here are the steps to find the missing frequency in a histogram:

1. First, you need to understand the total frequency. This is usually given or can be calculated by adding up all the given frequencies.

2. Next, calculate the total frequency of the given range. This can be done by multiplying the frequency of each class by the class width and then adding them all up.

3. Now, subtract the total frequency of the given range from the total frequency. This will give you the missing frequency.

4. If there are more than one missing frequencies, you would need additional information to find them. For example, if you know the mean or median, you can use that information to find the missing frequencies.

Remember, this method assumes that the missing frequency is not from the extreme ends of the histogram. If it is, you would need additional information to find it.
