WebOct 23, 2024 · Numerical Data Variables. A numerical variable is a data variable that takes on any value within a finite or infinite interval (e.g. length, test scores, etc.). the numerical variable can also be called a continuous variable because it exhibits the features of continuous data. WebProbability is a mathematical tool used to study randomness. It deals with the chance of an event occurring. For example, if you toss a fair coin four times, the outcomes may not be two heads and two tails. However, if you toss the same coin 4,000 times, the outcomes will be close to half heads and half tails. shoop best secretWebAnswer to Give the numerical value of the statistic p shoop browser extension
