For four samples, there are 6 possible combinations of two: AB AC AD BC BD and CD. For example, for AB the absolute difference (|A-B|) is 36.00 – 34.50 = 1.50. Step 2: Use the following formula to ... 1.1: Basic Definitions and Concepts.

Five to seven items are usually used in the scale. The scale doesn’t have to state “agree” or “disagree”; dozens of variations are possible on themes like agreement, frequency, quality and importance. For example: Agreement: Strongly agree to strongly disagree. Frequency: Often to never. Quality: Very good to very bad.Summary statistics summarize and provide information about your sample data. It tells you something about the values in your data set. This includes where the mean lies and whether your data is skewed.
