Question

what determines the width of the bars in histogram​

Answer 1

Answer:

The bars are of equal width and correspond to the equal class intervals, while the height of each bar corresponds to the frequency of the class it represents. The histogram is used for variables whose values are numerical and measured on an interval scale.

Answer 2

Histogram

• Histogram is a graph of frequency distribution which is commonly used for graphical representation of frequency distribution.
• Histogram is a vertical graph whose area is proportional to the frequency of the distribution.
• The width of the bars in histogram is not uniform and changes according to the condition of the distribution.
• Generally the width of the graph is equivalent to the class interval size.
• The length of the graph would be the frequency for a equal class interval distribution or frequency density for unequal class interval
• Therefore, we can say that it is the class interval type that determines the width of the graph in histogram.
