Objective:
1. Create a histogram and a frequency table.
2. Create classes, and class widths
DATA:
FREQUENCY:
a. Select cells E2:E6
b. Type, but do not press enter: =FREQUENCY(A2:A41,D2:D6)
c. Press CTRL+SHIFT+ENTER and the array formula will be entered into each of the cells E2:E6 [If you have trouble with this shortcut then you will need to input this formula individually into each cell –do not drag for copy]. Check your frequency sum “n”.
HISTOGRAM:
a. Select cells E2:E6
Choose the Insert tab at the top.
Choose Column and the first Graph from the 2-D section (Clustered Column).
Go to Chart Layout section and choose Layout 8
iv. In the chart itself:
1. Click on Axis Title for X-axis. Change to name to Classes
2. Click on Axis Title for Y-axis. Change the name to Frequency
3. Click on Data or Chart Title. Change the name to Project One
4. Right-Click on the grid tick marks for the x-axis
a. Select Data Source
b. Click Edit in the category
c. Highlight cells C2:C6 from the spreadsheet
d. Click ok
5. Right Click anywhere within the columns and add Data Labels
i. Go to Print Preview.
i. Go to Page Set- up and choose Landscape then
ii. Go to Margins tab.
1. Right & Left Margins= 0.75; Top Margin = 0.6 and Bottom Margin = 0.5
iii. Go to Page tab and choose Fit
iv. Go to Header/Footer tab and choose Custom Header
