College of Micronesia-FSM: Dana Lee Ling's Introduction to Statistics Using OpenOffice.org, LibreOffice.org Calc, 4th edition: "Section 2.3: Shapes of Distributions”
The shapes of distributions have names by which they are known.
One of the aspects of a sample that is often similar to the population is the shape of the distribution. If a good random sample of sufficient size has a symmetric distribution, then the population is likely to have a symmetric distribution. The process of projecting results from a sample to a population is called generalizing. Thus we can say that the shape of a sample distribution generalizes to a population.
Endnote: Creating histograms with spreadsheets
Making histograms with OpenOffice.org Calc 2.3, 2.4
Select both the column with the class and the column with the frequencies.
Click on the chart wizard button and then drag the mouse to place and size the histogram.
At the first dialog box be sure to click on the "First column as label" check box as indicated by the arrow in the diagram below.

Note on Ubuntu 9.10 OpenOffice.org Calc 3.1
The chart wizard for OpenOffice.org 3.1 running on Ubuntu 9.10 will not produce a two-dimensional column chart from a "split selection." This complicates producing a relative frequency chart. To produce a relative frequency chart, select all three columns and then delete the frequency column.
In step three, remove the frequency series to chart only the relative frequency.
