Math Tutoring on Bar Graph
Presenting Categorical Data Graphically:
Categorical or Qualitative data are pieces of information that allow us to classify the objects under investigation into various categories.
A Bar Graph is a chart that uses either horizontal or vertical bars to show comparisons among categories.
Guidelines for construction of a Bar Graph by Math Tutoring:
To construct a Bar Graph, we need to draw a vertical axis and a horizontal axis. The vertical axis will have a scale and measure the frequency of each category. The horizontal axis shows the categories. The bar height shows the frequency.
A Histogram is bar graph that represents a Frequency Distribution. The width represents the interval and the height represents the corresponding frequency. There are no spaces between the bars.
