Calculators

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

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.

Calculates the range (+/-) around a sample statistic (like mean or proportion) that likely contains the true population parameter.

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

This calculator determines the F-statistic, a value used in ANOVA (Analysis of Variance) to compare the variances of two or more samples. It helps determine if the variances are significantly different.

Calculates the sample proportion (p̂), which is an estimate of the population proportion. This calculator helps determine the proportion of a sample that possesses a specific characteristic.
