A "distribution of differences between means" can be thought of as a distribution of as:
A)difference scores, in which the difference scores are found by subtracting a series of sample means from the population mean
B)the differences you find when you use several methods, in sequence, of estimating the population mean
C)the differences you get when you repeatedly draw a sample mean from one population and a sample mean from another population and subtract one mean from the other
D)the differences between a single sample from Population 1 and all possible samples from Population 2

A distribution of differences between means is created by repeatedly drawing a sample mean from one population and a sample mean from another population, and then subtracting one mean from the other. This allows us to compare the means of two populations and determine if there is a significant difference between them. Choice A describes a distribution of difference scores, but not specifically between means. Choice B describes a distribution of differences when estimating population means by different methods, which is not the same as comparing means of two populations. Choice D describes a specific comparison between a single sample from one population and all possible samples from another population, which is not the same as comparing means of two populations.
