Exam 4: Quantitative Research: Descriptive and Correlational Designs

When developing a response scale, one should strive to make the response alternatives symmetrical in phrasing.

The level of significance required in most circumstances to conclude that a relationship is "statistically significant" is:

Which of the following is the type of statistics used to draw conclusions about the relationship between variables?

The burden of proof is highest for which of the following claims regarding the relationship between two variables?

The level of significance is the probability that a relationship between variables might be due to chance or measurement error.

What conclusion could you draw from the (hypothetical) data in the following correlation matrix? ** P<.001 *p<)05

If ice-cream sales and temperature both increase during the summer months, there is a ___________correlation between these two variables.

When writing a survey question, it is important to use double-barreled questions.

Violent crime and temperature both increase during the summer months. From this relationship we can conclude that:

Researchers hypothesized that the new "Shake Weight" would yield a more effective workout than traditional barbell weight training. They found that using the "Shake Weight" for 6 minutes a day, three times a week, resulted in the greater improvement in strength than engaging in a 40-minute barbell regimen three times a week. They acknowledged, however, that they might have a Type I error. What does this mean?

Likert scales are 7-point scales.

The statistic used to measure the association between two nominal variables is:
