What is a statistical question and what is its purpose? Be sure to include the 3 characteristics. That makes it up.

The purpose of a statistical question is it is the first step of the statistical process. The 3 characteristics  of a statistical question are allows for clear responses, includes a specific population, and anticipates variability of the data.

Well a dot diagram is like this for example,

And a histogram is this,

Dot diagram uses dots and the histogram uses bars.

When would we use them? Well that I can explain, you can use the dot diagram  to see what pets people have or even to see how many people scored how many points.

A histogram can be used for a concert. There would be like on the bottom,  0-6, 7-12, and so on. The bars show how many people from what age group are joining the concert.

Explain the difference between center and shape of a data set.

The center is the median and/ or mean of the data. The spread is the range of the data. And, the shape describes the type of graph.
