Question

What type of graph to use? Example: Data were obtained on the percent of alcohol (such as 13.28, 12.69, etc.) in wine produced from the same variety of grape in the same year by 48 winemakers in the same region of Italy. The researcher wishes to determine the shape of the distribution of the percents and the number of modes in the data. What graph is the most appropriate way to describe the data set?

A. Histogram
B. Line graph
C. Bar chart
D. Scatter plot

Answer 1

The most appropriate graph to describe the data set is a histogram. Changing the number of bars in the histogram will affect the shape of the graph.

Step-by-step explanation:

The most appropriate graph to describe the data set is a histogram. A histogram is a graphical representation of the distribution of a dataset. It displays the values of the data on the horizontal axis and the frequency or percentage of those values on the vertical axis. In this case, the histogram will show the distribution of the percents of alcohol in wine produced by the winemakers.

Changing the number of bars in the histogram will affect the shape of the graph. If there are more bars, the graph will have more detail and may reveal smaller variations in the distribution. Conversely, if there are fewer bars, the graph will have less detail and may smooth out the distribution.
