Question

I want to make sure that my answers are correct. My answer are in bold.

varies with the independent variable such that its effects on the dependent variable cannot be separated from the independent variable

		secondary independent variable
		control variable
		degrees of freedom
		confounding variable

A good scientific theory that uses relatively few constructs to explain many empirical findings is called ________________

		sampling bias
		power
		sampling error
		parsimonious

research design where each subject receives (or experiences) each level of the independent variable

		construct validity
		within-subjects design
		correlational research
		between-subjects design

sampling distribution of the mean becomes approximately normal as sample size increases

		central limit theorem
		third-variable problem
		confidence interval
		one-tailed test

symmetrical, bell-shaped distribution that represents many real-world characteristics

		alternative hypothesis
		normal distribution
		sampling bias
		empirical data

research design where different groups of subjects are used for each level of the independent variable

		within-subjects design
		between-subjects design
		construct validity
		inferential statistics

a measure of the consistency between two different assessments

		point estimate
		validity
		degrees of freedom
		reliability
