A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph
represents categories on one axis and a discrete value in the other
. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.
How do you describe a bar graph?
A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips. Bar graphs are used to
compare
and contrast numbers, frequencies or other measures of distinct categories of data.
What do bar graphs tell us?
Bar graphs are ideal for
comparing two or more values, or values over time
. Data is displayed either horizontally or vertically. Single bar graphs are used to convey discrete values of an item within a category. For instance, a bar graph could display the number of males with a certain trait for specific ages.
When should you not use a bar graph?
Don’t use a bar graph
to compare items that require different scales
. Because that will complicate your message. You should also avoid using bar graphs to show percentages that add up to a whole if they aren’t broken down over time. Because those would be…
What are the advantages of bar graph?
- show each data category in a frequency distribution.
- display relative numbers or proportions of multiple categories.
- summarize a large data set in visual form.
- clarify trends better than do tables.
- estimate key values at a glance.
- permit a visual check of the accuracy and reasonableness of calculations.
How do you describe a bar graph example?
A bar chart uses
either horizontal or vertical bars to show comparisons among two or more categories
. … One axis of the chart shows the specific categories being compared, and the other axis of the graph shows a given value (usually a percentage or a dollar amount).
How do you start to describe a graph?
- UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
- DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
- UP & DOWN: fluctuate / undulated / dip /
- SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.
What is a simple bar graph?
A simple bar chart is
used to represent data involving only one variable classified on a spatial, quantitative or temporal basis
. In a simple bar chart, we make bars of equal width but variable length, i.e. the magnitude of a quantity is represented by the height or length of the bars.
When should you use a bar graph?
Bar graphs are used to
compare things between different groups or to track changes over time
. However, when trying to measure change over time, bar graphs are best when the changes are larger.
What can I use instead of a bar graph?
- Row chart. “Hang on,” you might say, “this graph looks awfully familiar.” …
- Radial column chart. The radial column chart is a bar graph that’s been curled around on itself. …
- Donut chart. …
- Stacked row chart. …
- Bubble chart. …
- Dot matrix. …
- Pictograms. …
- Choropleth.
When would you use a circle graph instead of a bar graph?
Circle Graphs to Bar Graphs
Circle graphs are most useful
when comparing parts of a whole or total
. Bar graphs also make comparisons easily. Unlike most circle graphs, bar graphs compare exact amounts. Circle graphs are used when dealing with percentages, and the percentages of the pieces add up to 100 percent.
What is a disadvantage of a bar graph?
Disadvantages: Bar charts
that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message
. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant.
What are the disadvantages of graphs?
What are the disadvantages of graphs? The major disadvantage of using charts and graphs is that these
aids may oversimplify data
, which can provide a misleading view of the data. Attempting to correct this can make charts overly complex, which can make their value in aiding a presentation less useful.
What are the disadvantages of line graphs?
- Plotting too many lines over the graph makes it cluttered and confusing to read.
- A wide range of data is challenging to plot over a line graph.
- They are only ideal for representing data that have numerical values and total figures such as values of total rainfall in a month.
