There are three quartiles denoted by Q 1, Q 2 and Q 3 divides the frequency distribution in to four equal parts. You see where were going. A frequency histogram is used to graph this continuous data. P{X = k} = n! To get the standard deviation of a random variable, take the square root of the variance. And you might be A quantitative or Numerical variable is a type of variable consisting of values that represent counts or measurements of a certain quantity. This means that we perform the random experiment and obtain , and then the value of is determined as . THe reason why is because we can use the tools of calculus to analyze population growth, and also because the sample space is so large (in the millions or billions), that it is relatively continuous. Are there any outliers? You could not even count them. The number of patients in a hospital. In comparison to discrete data, continuous data give a much better sense of the variation that is present. - Definition & Examples Quiz, What is Categorical Data? It could be 1992, or it could Discrete random variables can only take on a finite number of values. Each issue focuses on one specific area that bridges mathematical, physical and other sciences.
