Calculators

Calculates the proportion of times an event occurs within a dataset (Frequency / Total).

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

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

Calculates the five-number summary (Minimum, First Quartile, Median, Third Quartile, Maximum) from a set of data, which is used to create a box plot.

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

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