Platykurtic means that the distribution has fewer outliers and a flatter peak than a normal distribution. A distribution with a mean of 10 and SD of 5 will have more outliers and a more spread-out peak than one with a SD of 2, which is closer to a normal distribution. Therefore, the distribution with a SD of 5 is much more platykurtic than the one with a SD of 2.
