      Q: How Do You Calculate the Midpoint Riemann Sum?

      A: A Riemann sum is a method of approximating the area under the curve of a function. It adds together a series of values taken at different points of that function and multiplies them by the intervals between points. The midpoint Riemann sum uses the x-value in the middle of each of the intervals.

    • Why Are Points Connected in a Line Graph but Not in a Bar Graph?

      Q: Why Are Points Connected in a Line Graph but Not in a Bar Graph?

      A: A line graph is a graph that charts the relationship between two variables or a progression of a single quantity through time. Without the lines connecting points of data, it would be difficult to make sense of the data being presented if there was no overall trend between the dots. A bar graph, on the other hand, is meant to compare two or more statistics, such as population figures.
