What is the difference between Bar chart and a frequency histogram?

In a bar chart,, each column represents a group defined by a categorical variable; and in a histogram, each column represents a group defined by a quantitative variable.
Example, in a histogram of income people earn according to their ages, the columns would represent the ages, For example, the first one might be 18-21, and the next one 22-25 etc and the the the amount made would be on the vertical or y axis.
You could have a bar graph of income vs color of your hair and each bar might be a color So once again, the labels on the bars might be redhead, blond, black hair, etc. and the numbers on the y axis would be the income. The point of the example is that in the bar chart, the columns are groups defined by hair color for example which is a categorical variable. It could just as well be states in the US or many others. And in the histogram, the variables is quantitative. We used age.
They are very similar and the important difference is often subtle at firsts.

What is the difference between graph and histogram?
A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.
What is the difference between bar diagram and historgam?
A histogram when plotted as a bar diagram, shows the frequency or relative frequency of a set of data. An example of bar chart that is not a histograms would be a plot of the average salary of Americans from 1980 to year 2000. However, if the salaries were broken into groups, and a chart showed the number or percentage of Americans making less than $100,000 and those making more, this would be a histogram.
Can you find the measures of center only from the histogram?
No. You can do that from a bar graph, a stem and leaf chart, a scatter plot, a cumulative frequency chart.
What is the difference between a histogram and a pareto chart?
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.
Difference between histogram and bar chart?
A histogram is one kind of bar chart.Bar chartsIf we want to represent the data collected about qualitative variable then a bar chart is the simplest method to employ.The gaps between the categories in a bar chart are important: they emphasise the fact the categories used are mutually exclusive and do not form a continuum.HistogramsLike bar charts, a histogram is produced by sorting data into categories (called bins). However, unlike a bar chart, the values on the x-axis form a continuum: the point at which one bin ends is the point at which the next bin begins. For this reason, neighbouring bars in a histogram must touch. In a bar chart, frequency is expressed as the height of the bar; whereas in a histogram it is expressed as the area of the bar.Unlike a bar chart, where the gaps between the bars stress the absence of a continuum on the x-axis, the gaps in a histogram have a different meaning. Because the x-axis is a continuum, a gap in the data indicates that there were no data values in this bin.The shape of the histogram depends on the choice of x₀ and the bin-width, and making the wrong choice can led to flawed interpretations. Too many bins and you cannot see the structure of the data properly due to the presence of too much information; too few bins and you cannot see the structure at all. There are various methods for choosing the ideal bin-width, but none is definitive.Also, Both are used differently.

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 type of graph would be needed for a mode calculation?
For discrete data, a bar chart. For continuous data a grouped frequency chart (histogram).
What is a bar chart that depicts the frequency of occurrance-by the height of the bars-of numerical or measurement categories of data?
Histogram

Difference between histogram and frequency polygon?
They are the same thing except that in a histogram you are using bars (like in a bar chart) to show the frequency, while a polygon uses points connected by straight lines The way I have the students do it is to plot the x,y coordinates for your data ( x is the value of the random variable, y is the frequency ) If you are doing a frequency polygon, you just connect the dots with straight lines (you need to start at zero to the left of your first point and to the right of your last point) If you are doing a histogram, just draw bars where the middle of each bar comes up to the x,y point
Is a histogram a special kind of stem and leaf plot?
no a histogram is a chart
What is a histogarm?
A histogram is a kind of bar chart in which the bars are not all of the same width, and the heights of the bars are such that the area of each bar represents the frequency for that category.
