The second distribution is far more peaked than the first.

Kurtosis (from the Greek word κυρτός, kyrtos or kurtos, meaning bulging) is a measure of the "peakedness" of the distribution of sample data. Positive kurtosis (leptokurtic) indicates more peakedness than predicted by a normal distribution, and negative kurtosis (platykurtic) indicates less peakedness than a normality distribution. 0 would indicate that the peakedness was as expected for a normal distribution.
