you have to find the class size by:

(max-min)/number of classes

Then use that class size to setup the class ranges

Then use the class ranges to determine the frequency a sample occurs in each class.

make a chart using the class ranges and the sample frequencies to display the histogram

Are you talking about a histogram of the relative frequency distribution.


What is the difference between a frequency histogram and a relative frequency histogram?

Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.

How are histograms and bar graphs different?

In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"


What is the mode of grouped and ungrouped data?

If you have calculated a histogram of your data, the mode is the interval with the highest relative frequency. If you have not created a histogram, and your dataset contains finite numbers (fixed decimal numbers), with some numbers repeating, then those numbers that repeat the most would be the mode. Otherwise, if you do not group your data, where you select an interval to calculate relative frequency, then a mode is not identifiable.


What is the difference between a histogram and a pareto chart?

Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.

What is the difference between bar diagram and historgam?

A histogram when plotted as a bar diagram, shows the frequency or relative frequency of a set of data. An example of bar chart that is not a histograms would be a plot of the average salary of Americans from 1980 to year 2000. However, if the salaries were broken into groups, and a chart showed the number or percentage of Americans making less than $100,000 and those making more, this would be a histogram.


What is the Difference in relative frequency and percentage frequency?

Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.


What is the meaning of a relative frequency of 0?

Relative frequency of an event is the frequency of that event divided by the total number of observations. Therefore, a relative frequency of 0 implies the event has zero proportion (or probability).


The first class in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2What does the 0.2 value indicate?

The sum of the relative frequencies must equal 1 (or 100%), because each individual relative frequency is a fraction of the total frequency. The relative frequency of any category is the proportion or percentage of the data values that fall in that category. Relative frequency = relative in category/ total frequency It means a number in that class appeared 20% of the total appearances of all classes
