We can use a non-parametric test to evaluate nominal data. --- TRUE/FALSE

Given the following example, which test would you choose? correlation, t-test, z-test, or ANOVA

A sample of n = 14 individuals is selected from a normal population distribution with µ = 70 and σ = 10. A treatment is administered to the individuals in the sample, and after the treatment, the sample mean is found to be M = 75.

Given the following example, which test would you choose? correlation, t-test, z-test, or ANOVA

A researcher is interested in examining the relationship between birth-order position and personality. A random sample of n = 18 individuals is obtained & each individual is classified in terms of birth-order position as first-born or only child versus later-born. Then each individual's personality is classified as either introvert or extrovert and the relationship of these two variables are calculated and communicated using a scatter-plot to indicate relationship.

If you were to review research results and saw the notation and corresponding value of r = .60, which test did the researcher use to evaluate the data? -- correlation, t-test, z-test, or ANOVA

The distance between a single score and the mean is known as a ______ score, and the average distance of all scores from the mean is known as the ______ ______   .

When converting raw scores to z-scores or standard scores, the value for the mean is always ______   and the value for the standard deviation is always  _______.

Given the following example, which variable is the independent variable? -- indoor lighting, depression, depends upon the outcome of the experiment, or winter months

The results from an experiment indicate that increasing the amount of indoor lighting during the winter months results in significantly lower levels of depression.

Given the following example, which is the dependent variable? -- depressive episodes, heart surgery, depends upon the outcome of the experiment, or post-operative regimen

A clinic tested a new post-operative regimen to see if it would decrease depressive episodes after heart surgery.

For an ANOVA problem, if you calculate an f-ratio of 9.571 and your f-value identified in your f-distribution table to determine critical region is 10.13, would you reject the null or fail to reject the null hypothesis?
