Mathematic characteristics of the sample.

What are statistics?

100

The z score associated with a confidence level of 95%.

What is ±1.96?

100

Differences that did not occur by random chance.

What are significant differences?

100

Samples must be mutually exclusive and independent of one another.

What is independent random sampling?

100

The sampling distribution for the ANOVA test.

What is the F distribution?

200

When we can learn about large groups (populations) by looking at smaller groups (samples).

What is a inferential statistics?

200

The alpha level associated with a confidence level of 95%.

What is .05?

200

There is no difference.

What is the null hypothesis?

200

The denominator of the z formulas when testing for differences between two populations by way of two samples.

What is the pooled estimate?

200

ANOVA is appropriate for situations in which we are comparing ______.

What is three or more samples?

300

Dividing the population into traits to select your sample.

What is stratified sampling?

300

The percent that we are wrong and our interval does not contain the population mean/proportion.

What is alpha level?

300

The difference is real.

What is the alternative/research hypothesis?

300

When conducting a hypothesis test in one direction.

What is a one-tailed test?

300

Use this to find your critical F-score.

What is Appendix D?

400

The mean of this theoretical distribution is equal to the mean of the (unknown) population.

What is the sampling distribution?

400

Unless told otherwise, Pu always equals ______.

What is .50?

400

If the obtained z score falls in the critical region, we will ______ the null hypothesis.

What is reject?

400

If the obtained z score does NOT fall in the critical region, we will ______ the null hypothesis.

What is accept (or fail to reject)?

400

To calculate the mean square estimates, we must divide our sum of squares by _______.

What are degrees of freedom?

500

Our sample should be ________ of the population of interest in order to make inferences/generalizations.

What is representative?

500

This is also sometimes called a "margin of error."

What is a confidence interval?

500

We use this distribution when our sample size (N) is less than 100.

What is the [student's] t distribution?

500

The research and null hypotheses _____ each other
