Statistics Test #1 Check List

GENERAL

This check list is to help you prepare for the upcoming test. It is not inclusive of all that you have to know, but is a memory jogger of some of the things that might have slipped your mind. This is also not a substitute for reviewing your notes and the book.

The test will not be utilizing a computer, but you will need a calculator (no sharing). The graphs are to be done in pencil using a ruler and erasing neatly if necessary. Graphs have to be clear and easy to read. You will need a protractor. Neatness counts. You will not need a compass. In all cases, when calculations are necessary, you must show the calculations on paper. Be precise in drawing and measuring; be accurate too.

For all graphs that we learned about, you need to know their use, their characteristics, and how to read as well as generate them.

HISTOGRAMS

Given raw data know how to break them into a given number of categories, and be able to make a frequency graph. Also be able to make a similar graph showing relative frequency. Remember that every graph has to have a title, and the x and y axes have to be label re value and units used.

BAR GRAPHS

Like Histograms above.

PARETO GRAPH OR PARETO DIAGRAM

You need to be able to make one of these whether you are given quantities or percentages.

CIRCLE GRAPH OR PIE CHART

You might be given quantities or percentages, but you will have to calculate the number of degrees for each item. If the data you are given requires you to add a category called “other,” then you need to do so.

LINE GRAPH

As above.

LAST MINUTE THOUGHT

Be careful and concentrate on what you are doing. A distracted mind leads to careless mistakes.
