What does the width of each bar in a histogram corresponds to?
The class interval.
What does each bar in a histogram represent?
I think it represents a frequency.
How do you form a frequency polygon from a frequency diagram?
Identify the midpoint of the top of each bar of the frequency diagram. Join these together and they will form a frequency polygon. Sometimes the polygon is extended down to the horizontal axis to where the midpoints of the bar before the first bar would have been and where the bar after the last bar would have been.
What is the difference between bar and histogram?
Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.
When representing a frequency distribution with a bar chart which bar will be the tallest?
A bar representing a frequency of (The Biggest #)
Each bar in a what indicates the frequency of an interval?
banana
What type of graph displays data from a frequency table and has one bar for each interval of the table that contains values?
histogram
What do you mean by histogram?
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.
What is a bar graph that shows the number of data items that occur within each interval?
It could be a bar graph or a frequency polygon. Or, if the intervals are of different sizes, a histogram.
What is histograma?
Histograma is a Spanish of histogram. Histogram is a bar graph in which data are divided into equal intervals, with a bar for each interval. The height of each bar shows the number of data values in that interval.

What type of scale is the bar graph scale?
On the "category axis", the scale may be nominal, ordinal, interval or ratio scale. On the frequency axis the scale must be numerical.On the "category axis", the scale may be nominal, ordinal, interval or ratio scale.
