A reading interval is a range of values in a dataset that contains a specific number of data points. This means that each value in the range is counted by the number of values in the interval.
For example, consider the following chart:
| Value | Frequency |
|---|---|
| 10 | 2 |
| 15 | 3 |
| 20 | 4 |
| 25 | 5 |
| 30 | 2 |
From the chart, we can see that the range of values between 10 and 20 contains 4 data points. This means that the interval between 10 and 20 is an interval with a count of 4.
Reading counts from a chart involves finding the sum of the frequencies in each interval in the chart. In the above example, the sum of the frequencies in the range between 10 and 20 is 2 + 3 + 4 + 5 = 12.
Reading intervals and counts from a chart is useful for understanding the distribution of data and identifying patterns in datasets. By examining the ranges of values and the corresponding counts, we can gain insights into the shape and characteristics of the data distribution
