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"

How are bar graphs and histograms and pie graphs similar?

they all compare different amounts


What graph is used for illustrating frequencies?

Most graphs: Pie charts, bar graphs, histograms, scatter graphs can all be used.


Which types of graphs are used for data from an interval scale?

Data from an interval scale can be effectively represented using line graphs, bar graphs, and histograms. Line graphs are particularly useful for displaying trends over time, while bar graphs can compare different categories. Histograms are ideal for showing the distribution of continuous data. Each of these graph types allows for meaningful interpretation of interval data, highlighting relationships and patterns.


Graphs that use bars or wide lines to compare data visually are called what?

Bar charts or histograms.


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.


What is the similarity between bar graphs and histograms?

they both use bars to show data and show ranges of data aswell.


What are five types of representational graphs?

Five types of representational graphs include bar graphs, line graphs, pie charts, scatter plots, and histograms. Bar graphs are used to compare discrete categories, while line graphs show trends over time. Pie charts represent parts of a whole, scatter plots display relationships between two variables, and histograms illustrate the distribution of numerical data. Each type serves a unique purpose in visualizing data effectively.


How are bar graphs and line graphs and circle graphs different?

circle graphs add up to 100% , bar and line graphs don't


Can you do graphs or tables in Qualitative research?

Yes. Histograms, for example.


What are the different graph options available for visualizing data?

The different graph options available for visualizing data include bar graphs, line graphs, pie charts, scatter plots, and histograms. Each type of graph is used to represent data in a specific way, such as showing trends over time, comparing categories, or displaying distribution.


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.


How many different graphs are there?

Bar, Line, Pie
