- 10 definitions. The definition is provided and you should provide the term best defined. The vocabulary lists at the end of the chapter is a good place to start. I would also pay attention to the terms defined in class (maybe one in particular that is in the Exercise B problems and was not written on the board but generated using Quattro Pro and is pronounced differently than it looks).

- Identify the level of measurement (Nominal, Ordinal, Interval, or Ratio). The levels of measurement are provided on the exam. There are four parts. Some of these are straight out of the textbook.

- Problems 9 - 18 in section 1.2

- Identify the type of sampling used. There are five sampling procedures described. You need to identify the type of sampling used. The types of sampling are provided on the exam.

- Multiple choice with 4 parts. More than one may be correct. Some statements are made about the mean. Decide which are valid.

For additional information, try:- Table 2-6 in section 2.4

- Multiple choice with 4 parts. More than one may be correct. Some statements are made about the sample variance. Decide which are valid.

- Multiple choice with 4 parts. More than one may be correct. Some statements are made about the abuses of statistics. Decide which are valid.

For additional information, read section 1.3 - 7
- The mean, median, range, variance, and standard deviation are given for a set of values. Some transformations are applied to the data, and you need to determine what the new value for the mean, median, range, variance, and standard deviation will be. There are three transformations: One is adding (or subtracting) a constant to all the scores, the second is multiplying (or dividing) all scores by a constant, and the third is a combination of subtraction and division (hint - check out Z-scores).

- You're given a small sample (n=20) and asked to create a frequency table from this data. You're told the number of classes, but have to decide upon the rest based on the data. You need to complete the lower class limit, upper class limit, class mark, and frequencies. Then, you must find the mean and standard deviation for the grouped data (not the original values) using your calculator.

- Given a small (12 - 15 scores) set of data, you need to find some statistics. You will need to find eight (8) of the following: mean, mode, median, midrange, range, standard deviation, variance, minimum, maximum, quartiles, percentiles. For the mean, standard deviation, and variance, be sure you know how to find them on your calculator.

For additional problems of this nature, try the following locations:- Quartiles / Percentiles (remember to
**rank**the data first) : Problems 17 - 20, 24 in section 2.6 - Range, Standard deviation, Variance: Problems 1 - 6 in section 2.5
- Mean, Median, Mode, Midrange: Problems 1 - 6 in section 2.4 (note - this is the same data used for 1-6 in 2.5)

- Quartiles / Percentiles (remember to

I will allow the class to work in pairs on part of the test if the following requirements are met:

- At least half of the class must provide the answers to the questions below.
- Problems 1 - 6 must be done as individuals and turned in.
- When problems 1 - 6 are turned in, you may pick up problems 7 - 9 and work with one other person on this part.
- There is no requirement to work with someone else, you may work alone.
- Each person needs to turn in a copy of the second part regardless of whether they work with someone or alone.
