WebProbability density function (pdf) The probability density function is given by: X is the random variable. μ is the mean value. σ is the standard deviation (std) value. e = 2.7182818... constant. π = 3.1415926... constant. Cumulative distribution function The cumulative distribution function is given by: X is the random variable. WebPearson's coefficient of contingency is defined as following: The coefficient varies between 0 (no relationship) and 1 (strong relationship) depending on a size of the table (for a 2 × 2 table the maximum value is 0.707). That’s why it should be used only to compare tables with the same sizes.

He surveyed a random sample of 120 120 guests and asked them which floor their room was and about their level of satisfaction. Here are the results: start box, 23, end box. Rashad wants to perform a \chi^2 χ2 test of independence between floor and satisfaction.
