    Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
  • Probability distribution function (pdf):
    Function for mapping random variables to real numbers.
    Discrete random variable: Values constitute a finite or countably infinite set.
Basic descriptive statistics is the procedure of encoding various properties of the distribution in a few numbers. Median: the point with 50% probability above 

What is basic descriptive statistics?

Basic descriptive statistics is the procedure of encoding various properties of the distribution in a few numbers

Median: the point with 50% probability above & 50% below

(If a tie, use an average of the tied values

) Less sensitive to tails! Variance of a data sample (regrettably has same notation as variance of a distribution---be careful!):
