Can someone please explain how to find the frequency from:

Lower limit:230,240,250
upper limit:239,249,259
Mid Value:234.5,244.5,254.5

To find the frequency in a given data set with lower limits, upper limits, and mid values, you can use the following steps:

1. Calculate the class width:
The class width is the difference between the upper limit and the lower limit. In this case, subtract each lower limit from its corresponding upper limit.
Class width examples:
- For the first set of data: 239 - 230 = 9
- For the second set of data: 249 - 240 = 9
- For the third set of data: 259 - 250 = 9

2. Calculate the frequency:
The frequency represents how often a certain value appears in the data set. In this case, we can calculate the frequency by dividing the class width by the difference between the mid value and the lower limit.

For example, using the first set of data:
- Class width: 9
- Mid value: 234.5
- Lower limit: 230

Frequency = Class Width / (Mid Value - Lower Limit)
= 9 / (234.5 - 230)
= 9 / 4.5
= 2

Therefore, the frequency for the first set of data is 2.

Repeat this calculation for all sets of data using the respective values.

So, to find the frequency from the given data, determine the class width for each set and then calculate the frequency using the formula provided.
