What do you think is the shape of the distribution of the age at which a child takes its first steps

Symmetric

Explanation:

The majority of children start walking at one and a half years so when the distribution is plotted on a histogram, it will be symmetric and unimodal. This means that it will have a single peak that is approximately 18 months.

This kind of distribution is a normal distribution and will have a shape similar to the one in the above diagram. This contrasts another type of distribution, the uniform distribution, when any value is possible, such as plotting the value of a card drawn from a complete deck.
