A histogram is used to show the distribution of a variable. and we use the bar for respective bins since there are no gaps between bins as a result no gaps between bar too. A histogram is used to show quantitative data while a bar chart is used for categorical data.
Nominal scale is used for quantitative data where number have no values.
example- Mild , strong , moderate
Cumulative frequency is the sum of the class and it is not possible to add mild and mild. I mean if two mild adds together then what will be the value? not possible to show.

What is the difference between a bar chart and a histogram? Why are the bars separated in the former but not in the latter? What types of variables are appropriate for each? As a class, discuss a classification scheme for deciding what type of graphic device to use for for the following types of variable: discrete, dichotomous, nominal, ordinal, interval/ratio, and continuous. Is there any additional information that would be useful to consider toward helping students to avoid confusing the...

The total area of the bars in a relative frequency histogram: A. depends on the width of each bar. B. depends on the sample size. C. depends on the number of bars. D. depends on both the sample size and on the number of bars. The most appropriate type of chart for determining the number of observations at or below a specific value is: A. a cumulative frequency ogive B. a pie chart C. a histogram D. a time-series chart

What is the main difference between a bar chart and a histogram to display data? a. Bars in a bar chart have space between responses, where histograms have no space between bars because the variables are ordinal (ordered). b. A bar chart displays descriptive statistics, where a histogram does not. statistics re a histogram does not. C. A bar chart should be used for ordinal data, a histogram should be used for dichotomous data. d. There is no difference between...

Graphing Given a histogram with a line for a normal curve superimposed on it, interpretation of the distribution of scores may be ambiguous. If the bars on the histogram are above the line for the normal distribution superimposed on the histogram, then the variable distribution is leptokurtic ("peaked"). If they are below the line, then it is platykurtic ("flat"). However, if the bars cross the line on only one side, then it is skewed. If they cross more on the...
