Excel For Mac Relative Frequency Histogram
Excel For Mac Relative Frequency Histogram Example

The FREQUENCY function requires two ranges. The first defines the range that contains the data; the second defines the range that contains the boundary values for our histogram bins. As is always the case, Excel lets you indicate range arguments in a function by highlighting the worksheet range with your mouse. You’re almost ready but.
Create a frequency distribution for the data using 7 classes, beginning at 115 lbs, with a class width of 10 lbs. List upper and lower class limits on the graph. With the frequency distribution develop the following charts o Frequency Histogram o Relative frequency distribution o Relative frequency histogram.
To create a frequency distribution and a histogram, follow these steps: Click the Data tab’s Data Analysis command button to tell Excel that you want to create a frequency distribution and a histogram. When Excel displays the Data Analysis dialog box, select Histogram from the Analysis Tools list and click OK.

The Importance of Histograms and Descriptive Statistics

Calculating descriptive statistics such as mean, median, and variance is easy, since Excel has functions for this purpose. Let’s look at something a little more complicated but a necessary tool in the statistician’s toolbox, the frequency distribution and its graphical comrade, the histogram. Creating a Histogram using Microsoft Excel.

The word “statistics” comes from the German word “stadt”. Stadt means “city” but in the 18^th century each city was a state in its own right. And the people who ran those states needed to have the facts. What is the population? What is the food production? How many men are available for the military? What is the birth rate? Information about the state came to be known as Statistics. In today’s complex world people do data mining, gather big data, and perform tests of statistical hypotheses. It is easy to forget that one of the primary tasks of statistics is purely descriptive.

We’ll stick with the centuries-old tradition and gather some information about cities, starting with a table of income information about cities in the United States from the year 2009. We would like to observe the frequency distribution of median family incomes. The Excel data analysis toolpak has a nice dialog box for doing this automatically, but we’re going to take charge and do it ourselves using the FREQUENCY function.

We must first define the bins, which is to say the value ranges into which our data will be sorted. Generally this is done in a worksheet column, and Excel’s auto-fill feature makes this easy. In this example we will create bins from 10,000 to 170,0000 at increments of 5000.

Now we are ready to tabulate our frequency distribution. We highlight a second column next to our column of bin values. In the formula bar, we enter =FREQUENCY(. The first argument is the range containing our data. If you enter this range by highlighting it on the worksheet, be careful not to include the column heading. Only the data is highlighted. The second argument to FREQUENCY is the range containing the bin values. After entering the range in the formula bar close the parenthesis, but

Do not hit enter!
Highlight the range where the frequency results will appear and enter the frequency function.

Enter both the data ranges and the frequency bin range.

You’re almost ready but

FREQUENCY if one of the many valuable Excel array functions. Mr. Excel calls them “CSE” functions, and this name is well chosen. The CSE acronym reminds us that you enter array functions not by hitting enter but by hitting <ctrl><shift><enter>. When you hit control-shift-enter, the formua will be entered in the highlighted cells. Note that in the formula bar, the function is now within curly braces. You cannot just type in these curly braces yourself. You must let Excel enter them after you type <ctrl><shift><enter>.

Now that we have our frequency distribution, it is impossible to resist creating a chart. The frequency range is already highlighted; we have only to click on “column chart” from Excel’s Insert ribbon tab. The chart looks OK, but we see that we will have to edit the horizontal axis label to reflect our frequency bins. We can right-click on the chart and choose “Select Data…” . Click the “Edit” button on the right-hand side, the side for the horizontal axis labels. Then enter the range containing the frequency bins.

Right-click the chart and choose “Select Data…” to edit the axis labels.

After entering a title and choosing a style, we have our finished frequency histogram!

I hope you enjoyed my first Excel post! Stay tuned for my next one where we cover Standard Deviations.

A histogram is simply a bar graph that shows the occurrence of data intervals into a bin range. Or say it shows the frequency distributions in data.
A histogram may look like a column graph but it is not interpreted from the column's height. It is intrepreted from the area it covers.
A bin is defined for frequency distribution. It is a kind of grouping.
For example, if you want to know, in a school, how many students are of age 5 or below, how many are between 6-10, how many are between 11-15, how many are between 15-20 and how many are 20 or more. The histogram in excel is
the best way to analyze and visualize this data and get the answer.

Enough of the theory, let’s dig into a scenario.

How to Make a Histogram on Excel 2016 Example:

Let's say that we have this data in excel.

In Column A we have Sr. No.
In Column B we have Age.
In Column C we have the age range or say it's our excel histogram bin range. It shows that we want to know the number of students whose age is:

age<=5, 5<age<=10, 10<age<=15, 15<age<=20 and age>20. Simple, isn’t it? It is used to produce a frequency distribution.

Now, to plot a histogram chart in Excel 2016, we will use Data Analysis add-in. I assume you have read how to add data Analysis Add-In Excel for adding Data Analysis Toolpak. If you have already added it in, we can continue to our histogram tutorial.

Make Histogram Using Data Analysis ToolPak

To create a histogram in Excel 2016/2013/2010 for Mac and Windows, follow these simple steps:

1. Go to the Data tab and click on Data Analysis.

1. 1. Select Histogram in Data Analysis ToolPak Menu Dialog and hit the OK button.

1. 1. 1. In Input Range, select your data. In Bin Range select the interval range. Now if you have selected headers then check Labels, else leave it.

Select the output range. The place where you want to show your histogram in Excel worksheets. For this example, I have selected E13 on the same sheet.

Check Chart Output checkbox for Histogram chart.

Press that OK button on top. It will plot a histogram on the excel sheet.

1. 1. 1. 1. Now we have created a histogram chart in Excel.

We need to do a little bit of editing in this chart.

1. 1. 1. Select the bar and right-click. Select the format chart area. In Excel 2016 you will see this kind of menu. It is different in older versions.

Click on the little bars shown. Reduce the gap width to 0%.
