The Kurtosis Calculator measures the degree of peakedness or flatness of a dataset’s distribution compared to the normal distribution. A positive kurtosis (leptokurtic) indicates a sharper peak and heavier tails, meaning more data values lie in the extremes, while a negative kurtosis (platykurtic) represents a flatter curve with lighter tails. A kurtosis value close to zero (mesokurtic) suggests a normal distribution. This calculator helps analyze data characteristics, detect outliers, and understand how data is spread relative to the mean.
