Exam 10: A Brief Course in Statistics

If the critical value of a chi-square statistic were 3.841,and the chi-square value you obtained in a statistical analysis of your data were 6.89,this would mean that:

Which of the following is a measure of dispersion?

The probability of an event is the total number of all specific outcomes that qualify as the event divided by:

As most inferential statistics (e.g. ,t values,chi square values,F ratios)become larger,the probability values (p values)associated with them:

The best term for the observations that are the subject of statistical analysis is:

Measures of dispersion provide information about:

The expected frequency for heads in a series of 100 tosses of a fair coin is:

How many total unique outcomes are there for a series of 10 fair coin tosses?

Most of the things that psychologists measure in their research approximate______ distribution.

If it is impossible to conduct a within-subjects design within a certain experiment,what else can the researcher do to detect a real effect?

It is easier to commit a Type II error when:

According to the text,a good way to avoid Type II errors is to:

Committing a Type I error means:

Which of the following is most likely to yield a clear and simple picture of how big a specific effect is?

Which of the following is NOT a descriptive statistic?

Why would a researcher want to conduct a meta-analysis of effect sizes?

Avoiding restriction of range and using within-subjects designs are two good ways to avoid making:

If you were to graph the six possible scores that can be obtained by rolling a single six-sided die,what type of distribution would you have?

Statistics are:

Estimates _______ size are useful to evaluate the magnitude and importance of specific research findings.
