Select the column of data you wish to create a frequency distribution with, including the column header.
With the data highlighted, under the Insert tab, click PivotTable.
In the PivotTable dialogue box, make sure that the correct range of data is selected, and select the location where you want your PivotTable to appear. Click OK.
Now, a blank PivotTable will appear in the specified location, and a pane titled PivotTable Fields will be shown on the right side of the window. The name of the highlighted column will appear in the upper portion of the Fields pane.
To create a frequency distribution of the qualitative variable you selected, drag the column name in the upper part of the Fields pane down to the area in the lower part of the pane with the label Rows. In the PivotTable, you will now see a list of the possible unique values within the data you selected.
Now, drag the same column name from the upper portion of the pane to the lower portion with the label Values. Make sure the variable in the Values area is summarized by count. This can be specified by clicking the dropdown arrow next to the variable name, and opening the Value Field Settings dialogue box. Once the correct functions are set, the count, or frequency, of each unique value in your selected data column will now be displayed in the table, thus making it a qualitative frequency distribution.
Select the column of data you wish to create a frequency distribution with, including the column header.
With the data highlighted, under the Insert tab, click PivotTable.
In the PivotTable dialogue box, make sure that the correct range of data is selected, and select the location where you want your PivotTable to appear. Click OK.
Now, a blank PivotTable will appear in the specified location. When you click on the PivotTable, a pane titled PivotTable Fields will be shown on the right side of the window. The name of the selected data column will appear in the upper portion of the Fields pane.
To create a frequency distribution of the quantitative variable you selected, drag the column name in the upper part of the Fields pane down to the area in the lower part of the pane with the label Rows. In the PivotTable, you will now see a list of the possible unique values within the data you selected. If your data is continuous, this table will probably have more rows than desired. This will be fixed when we group the data at the end.
Now, drag the same column name from the upper portion of the pane to the lower portion into the box with the label Values. Make sure the variable in the Values box is summarized by count. This can be specified by clicking the dropdown arrow next to the variable name in the Values box, and opening the Value Field Settings dialogue box. Select Count and click OK.
Once the correct functions are set, the count, or frequency, of each unique value in your selected data column will now be displayed in the table. However, since our data is continuous, we need to group the data by creating bins. Right click on a cell in the Row Labels column of the PivotTable, and select the Group option.
In the Group dialogue box, specify your desired starting and ending values as well as the class width, denoted by the term By:.
Click OK. Now, your data should be grouped into classes, and the frequency count of each class should be displayed in the PivotTable.
Organize the data into 2 columns, the labels on the left and the values for each label on the right
Select all the data and under the Insert tab, insert either a 2-D Column (vertical) or 2-D Bar (horizontal) graph.
You may edit the chart title.
To add axis labels, use the Design tab, Add Chart Element and select Axis Titles > Primary Horizontal or Axis Titles > Primary Vertical.
The data for each box plot should be in a separate column.
To create the box plot, select Insert and then Recommended Charts. Go to the All Charts tab and select Box & Whisker, then OK.
You can edit the Chart Title by clicking on it and typing in a new title.
If you are displaying more than one box plot, then you should add a legend. Using the Design tab, Add Chart Element, and select Legend. You have several options of where to place the legend on the chart.
The value of 1 along the horizontal axis can be removed by selecting it and deleting it.
Organize the data for your dot plot into a single column.
Highlight the entire column. Under the Home tab, click the Sort & Filter dropdown and select Sort Smallest to Largest. The smallest values should now be at the top of the column.
Create a new column next to your data column titled "Frequency". In the first cell of the Frequency column, enter the number 1. In the second cell, enter the following formula (cell references may vary depending on the location of the data in your spreadsheet).
=IF(A3=A2,B2+1, 1)
Since our data is sorted, identical values will be in adjacent cells. The above formula will count the number of occurrences of each value. Once you have finished typing the formula into the cell, press Enter, and then double click the small box at the lower right corner of the cell to apply the formula to the whole column.
Now, we will create a scatter plot using our two columns. Highlight all the data in both columns (excluding column headers), then navigate to the Insert tab, and insert an X-Y Scatter plot. Your chart should look like the following, but specific to your data.
This is close to a dot plot, but it needs a few tweaks. First, we need to format the x-axis to remove all the extra whitespace. Right click on the x-axis, select Format Axis, and then change the Bounds to fit your data (make sure you fit in all the data, and leave a small cushion of whitespace on either side) . You can also specify the increment of the x-axis by changing the Major Units variable.
Next, let's remove the y-axis. Since each dot represents a single occurrence, the y-axis is unnecessary since we can simply count the dots. Also, we will delete the grid lines since they also are not necessary.
Lastly, we need to resize the graph so that our dots appear to be stacked on top of one another. To finish it off, lets add a title for the x-axis and for the chart as a whole.
Organize the data into two columns. In the first column, enter the lower boundary of each class, but also include the upper boundary of the last class as the final entry. In the second column, enter the corresponding frequency values. There should be one less frequency value than there are boundaries, so in the frequency column, leave the cell corresponding to the first heart rate value empty and begin entering the frequency values in the cell that corresponds to the second heart rate value.
A | B | |
---|---|---|
1 | Heart Rate | Frequency |
2 | 56.5 | |
3 | 66.5 | 2 |
4 | 76.5 | 10 |
5 | 86.5 | 32 |
6 | 96.5 | 5 |
7 | 106.5 | 1 |
Footnote: Histogram convention is for intervals to include a left endpoint and exclude a right endpoint. However, since the heart rates are presented as integers, a decimal or fraction can be used to eliminate the possibility of overlapping bins.
Select the values in the frequency column, and insert a column chart.
Right click on one of the columns in the chart and select the Format Data Series option. Under the Series Options menu, reduce the gap width to 0%. Then, under the Fill & Line menu, add a border of appropriate weight around the columns.
Select the values in the Heart Rate column, and while holding down the Ctrl button, also select an identical amount of cells from the blank column to the right of the Frequency column. With the cells selected, copy them to the clipboard. Next, select the chart by clicking on it, and then in the ribbon at the top click Home tab > Paste dropdown menu > Paste Special. In the dialog box that appears, paste the data as a new series with the Values in Columns, and also check the Categories in First Column box.
Right click on one of the corners of the selection box (since there is nothing else visible to click on) and select the Change Series Chart Type option. Format Series 2 as a Line chart and check the secondary axis box.
Select the chart and click on the plus symbol that appears in the top right corner. Click the arrow to the right of the Axes option and check the box for the Secondary Horizontal axes.
Format the secondary vertical axis (right) so that the horizontal axis crosses at the automatic position.
Format the primary vertical axis (left) so that the horizontal axis crosses at the maximum axis value. This will turn the chart upside down. Now, delete the primary vertical axis (left) to return the columns to their upright position.
Format the primary horizontal axis (top) so that it uses no line, labels, or tick marks. Make sure both options under Tick Marks and the Label Position option under Labels are set to None.
Format the secondary horizontal axis (bottom) so the vertical axis crosses at the automatic position. Finally, set the axis position to be on tick marks.
Organize the data into 2 columns, the labels on the left and the values for each label on the right. (The labels are not required.)
Select the column of data values and under the Insert tab, insert a 2-D Line graph.
After inserting the graph, to update the x-axis data labels, right-click the x-axis labels and choose Select Data. Under the Horizontal (Category) Axis Labels press Edit and select the label values range. Click OK and OK.
You may edit the chart title.
To add axis labels, use the Design tab, Add Chart Element and select Axis Titles > Primary Horizontal or Axis Titles > Primary Vertical.
Select 3 columns of data and click Insert > Scatter or Bubble Chart and choose Bubble. The first column will be the x-axis values, the second column the y-axis, and the third column the size of the bubbles.
If the bubbles overlap too much you can scale them down by right-clicking the bubbles, selecting Format Data Series and changing the value in Scale bubble size to to something less than 100.
Use the Add Chart Element button on the Design tab to add axis labels if you wish.
Enter a header for your data in A1 and your data below in a single column starting in A2.

A list will be shown of all the unique values in the column (up to 10,000). When the checkbox for a value is selected, the rows where this column has that value will be displayed. You can select any number of these checkboxes at any time.
There are also Number Filters or Text Filters depending on the type of data that are useful for selecting multiple values which fit some certain criteria.
Say you have the numbers 1, 2, 3, …., 20 in a column of data and you have filtered this column to only the even values (2, 4, 6, …, 20).
If you want to sum these values, type =SUM( and select the visible range, you will end up with =SUM(A3:A21) which is equal to 209. This is also including the non-visible cells in the sum. To avoid this issue, you can use the SUBTOTAL function. =SUBTOTAL(109,A3:A21) will equal 110, the sum of only the visible cells. The 109 is the code to access the SUM function for visible cells. There are several functions for visible subsets built into SUBTOTAL.
101 – AVERAGE, 102 – COUNT, 103 – COUNTA, 104 – MAX, 105 – MIN, 106 – PRODUCT, 107 – STDEV.S, 108 – STDEV.P, 109 – SUM, 110 – VAR.S, 111 – VAR.P
In cell A1 type "=RANDBETWEEN(1, 897)" for example. 1 represents the smallest possible number to generate and 897 the largest.
Place the cursor over the bottom right-hand corner of cell A1, click and drag the box down as many rows as random numbers you desire.
