Is this an error? : “The results from a normal distribution are always centered around the mean or average value. This means that 50% of the values are below the mean, 50% are above the mean, and the majority of the values are close to the mean value.” Isn’t that the definition of the median? I know that the mean and the average are the same for a normal distribution.

Type your question above this line.

Hi @Fyodor_Fomichev

The normal distribution is symmetric about the mean, showing that data near the mean value are more frequent in occurrence than data far from the mean.

The lesson could be more specific about what is meant by 50% below and 50% above in a normal distribution context, and I think the author misses the point I mentioned in my first line. One can say that the difference between mean and median further reduces while talking about normal distribution.
