"A Pareto chart may look at first glance like a histogram, but there are two key differences. The first is that the x variable is categorical rather than numerical. For instance, the x variable may be type of defect. The second difference is that the bars are arranged in decreasing order of frequency."

∙ 14y agoThe Histogram is a summary graph showing a count of data points falling in various ranges. The effect is rough approximation of the frequency distribution of the data.
while
The Bar Graph shows the frequency of each element in a set of data. the height of each bar represents how many of that data element there are.

How are bar graphs and histograms and pie graphs similar?
they all compare different amounts
What is the similarity between bar graphs and histograms?
they both use bars to show data and show ranges of data aswell.
What graph is used for illustrating frequencies?
Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.
Difference between line and bar graphs and pictographs?
bar graphs use bars and pictographs use pictures
Which data is the best analyzed and communicated using histogram?
Histograms are like bar graphs but instead of being spaced, each bar is attached to the next. Histograms are ideal when you're trying to compare large amounts if data.

Graphs that use bars or wide lines to compare data visually are called what?
Bar charts or histograms.

What the difference between a pictograph and a bar graph?
pictographs have pictures bar graphs have bars
Can someone provide an explanation on why that is and maybe give an website on where you found it and How come in histograms the bars connect but not in the bar graphs?
Bar graphs are used for qualitative or discrete [quantitative] data. Values between the bar categories are not possible an to emphasise that, the bars have gaps between them. Conversely, histograms are used for continuous data and so the values on the "category" axis form a continuum. To illustrate this, the bars touch on another. I learned this well before the internet was widely available so did not need a website.
Why bar graphs are useful for comparing data?
bar graphs are useful for comparing data b/c you cn actually see what the difference is between them.
What is the difference between bar graph and block graph?
Bar graphs are when it goes up and blocks is jut l
How are histograms and bar graphs different?
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
What is the difference between a bar graph and a histogram?
What is the difference between a bar graph and a histogram?There are two differences, one is in the type of data that is presented and the other in the way they are drawn.In bar graphs are usually used to display "categorical data", that is data that fits into categories. For example suppose that I offered to buy donuts for six people and three said they wanted chocolate covered, 2 said plain and one said with icing sugar. I would present this in a bar garph as:Histograms on the other hand are usually used to present "continuous data", that is data that represents measured quantity where, at least in theory, the numbers can take on any value in a certain range. A good example is weight. If you measure the weights of a group of adults you might get and numbers between say 90 pounds and 240 pounds. We usually report our weights as pounds or to the nearest half pound but we might do so to the nearest tenth of a pound or however acurate the scale is. The data would then be collected into categories to present a histogram. For example:might be a histogram for heights (with the appropriate scale on the vertical axis). Here the data has been collected into categories of width 30 pounds.The difference in the way that bar graphs and histograms are drawn is that the bars in bar graphs are usually separated where in histograms the bars are adjacent to each other. This is not always true however. Sometimes you see bar graphs with no spaces between the bars but histograms are never drawn with spaces between the bars.
