Descriptive statistics calculator
Type or paste a data set —an Excel column too, with a decimal point or comma— and get every usual measure of a statistics course, with the formulas and the steps.
What you can do
- Central tendency: mean, median, mode, geometric mean and harmonic mean.
- Dispersion: range, sample (n − 1) and population (N) variance and standard deviation, coefficient of variation, standard error and mean absolute deviation.
- Position: quartiles, interquartile range and percentiles, by linear interpolation as in Excel.
- Shape: skewness and kurtosis; outliers by the Tukey fences.
- Data with frequencies, absolute, relative and cumulative frequency table, histogram and box plot.
