I used Monte Carlo simulations and relative efficiency curves to test which central tendency measure (average) and which method of confidence interval estimation perform best depending on the lognormal shape and sample size. Results from synthetic populations were then compared and validated using ...

How to analyze a skewed distribution Use the median: The median is more robust than the mean as a measure of central tendency. The median is the middle value in a distribution, where values are arranged from smallest to largest, which makes it resistant to outliers (very high or low values...
Then when you combine or average a person’s responses, you get a more accurate measure of their opinions. Let’s jump into how to create a Likert scale survey and what to do with your results. How to create a Likert scale survey Okay, so how do you craft a Likert scale survey that...
‘collective utility’ as a measure of the value that an apparently empirical statement or assertion P may carry.Footnote6P is released for public distribution so that whenever its flaw is recognised by an auditor, the statement’s collective utility may thereby become apparent, and the auditor ...
The mean, often referred to as the average, is a measure of central tendency in statistics. In Excel, the mean is calculated by adding up a group of numbers and then dividing the sum by the count of those numbers. It provides a single number that represents the center point or typical ...
The CV is a measure of variability, unlike the first four which are measures of the central tendency, so it can be used in addition to the other approaches. As you can see, many of the methods generate reassuringly similar results. Here’s another example using 15 responses to a 7 ...
You'll find two classifications to descriptive statistics in some pieces, and in some, you'll read about three. People can describe data in different ways. Below, we've classified descriptive statistics into four major types. Measures of central tendency A measure of central tendency also called...

(see above), the accuracy measure would only make sense when a posttest performance of 100% would reflect fully accurate performance on the four types of problems. For determining absolute accuracy, we hence used only the learners’ performance on the four problems that were isomorphic to the ...
