Basic GMAT Commentary For This Histogram-Like Bar Chart
This graph is a bar chart that acts kind of like a histogram, which is basically a bar graph that has specified items on the X-axis and a counter on the Y-axis. Here we have a counter on the Y-axis, but the X-axis is more a continuous representation of time in # of hours.
For example, you can read from this bar chart that for 6-7 hours of TV time per week were reported by 7 respondents.
Note that no respondents reported watching 8-10 hours of television. For the most part, most of the respondents reported watching in the 4-6 hour range.
