Question

constructing scatterplots
population of ohio
what relationship between the population of ohio and the number of years is displayed in the scatterplot?
as the number of years increased, the population stayed the same.
as the number of years decreased, the population decreased.
as the number of years increased, the population increased.
as the number of years increased, the population decreased.

Explanation:

In a scatter - plot, we observe the trend between two variables. Here, the x - axis represents years (increasing from left to right: 1930, 1950, 1970, 1990, 2010) and the y - axis represents population (in millions). As we move from left (earlier years) to right (later years) on the x - axis, the y - values (population) are increasing. For example, the point for an earlier year (say 1930) has a lower y - value (population) compared to the point for a later year (say 2010).

Answer:

As the number of years increased, the population increased.
