Question

Central tendency refers to the middle or central score in a distribution, such as the mean, median, or mode, while variability refers to the spread of the scores in the distribution, such as the range or standard deviation. These two measures provide a comprehensive description of the distribution of scores. Choice A is not accurate as both chance and error variance refer to sources of variability in experimental research rather than measures of scores. Choice C is not accurate as independent and dependent variables refer to different types of variables in a research study, not measures of scores. Choice D is not accurate as probability and significance are statistical concepts that refer to the likelihood of obtaining certain results in a study rather than measures of scores.
