Most of the time: mean less than median Measures of Skewness It’s one thing to look at two sets of data and determine that one is symmetric while the other is asymmetric. It’s another to look at two sets of asymmetric data and say that one is more skewed than the other. It can ...
What is data skewness?Data skewness is a measure of the asymmetry of a probability distribution of a random variable about its mean. What are the types of data skewness?The two types of data skewness are positive skewness where the data leans to the right of the mean, and negative skewness...
Skewness Definition. Skewness describes asymmetry of returns from the normal distribution. It can come in the form of negative skewness or positive skewness, depending on whether data points are skewed to the left (negative skew) or to the right (positiv
Face validity is about whether a test appears to measure what it’s supposed to measure. It is one of four types of measurement validity

In my stats class today, the teacher mentioned that curves can have different levels of skewness and kurtosis. She didn't go into any real detail explaining what this is, especially kurtosis. Could someone give me a brief explanation to help point me in the right direction as to what kurtos...
