Exam 14: Interpreting Data

In #53 above, what is the median number of hours studied?

When we generalize from samples to larger populations, we use ______________ statistics to test the significance of an observed relationship.

Compare and contrast the primary differences between inferential and descriptive statistics. Be sure to highlight the strengths and weaknesses of each.

Measures of dispersion are appropriate for which types of variables?

Which of the following is not a guideline for the presentation of tabular data?

Statistics that summarize data in manageable forms are known as __________ statistics.

Bivariate and multivariate analyses are aimed primarily at:

With respect to standard deviation, which of the following statements is not correct?

The type of weapon used in a crime is what type of variable?

By itself, any particular value for the standard deviation

While the linear regression model is important for descriptive purposes, its predictive value is limited.

Calculating rates is really pretty simple, what is not so simple in determining rates is deciding the:

A(n) ______________ indicates the percentage of cases that fall at or below some value.

When reporting findings, the choice of the ___________, or the total number of cases, depends entirely on the purposes of the analysis.

If there is a great amount of variation in a distribution, it is known as being ______________.

Tests of statistical significance should only be used when the relationships observed in data collected come from the whole population.

If the standard deviation is zero, we can conclude that:

Compare and contrast the primary measures of central tendency (mode, median, mean). What do each of these measures tell us about data?

High dispersion of a variable could result in:

A friend of yours assigned a code of 1 to "male" and a code of 2 to "female" on the variable gender. Your friend asked the computer to compute the average score on gender. The computer printout contained the following information: mean = 1.38, standard deviation = .432, median = 1.4, and mode = 1.0. You advise your friend that the best measure of central tendency for report is the:
