Usually the intervals in a frequency chart should be equal.
a tally chart with a intervals is a number between a point....
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.
They are not alive!
No.
Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.
If the intervals are of different width, then it is a histogram.
The most important thing in creating intervals for a frequency distribution is that the intervals used must be non-overlapping and contain all of the possible observations. They are often equal intervals, but sometimes unequal ones are used. It all depends on the data.
The augmented intervals chart provides information about the distance between notes in music that are one half step larger than a perfect or major interval.
Yes, you can.

A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.
