Calculators

Calculates the relative risk (RR) to determine the likelihood of an event occurring in an exposed group versus a non-exposed group.

Helps determine class intervals and frequencies for constructing a histogram (visual representation of frequency distribution).

Calculates the range within which a population parameter (e.g., mean, proportion) is likely to lie, with a certain confidence level.

Applies the 68-95-99.7 rule for data distribution within standard deviations of the mean for a normal distribution.

Calculates probabilities for the number of events occurring in a fixed interval of time or space.

Calculates the mean and standard deviation of the sampling distribution for sample proportions (p̂).
