What are the advantages and defect of different graphs?

When girlfriend are selecting to display screen data with graphs, walk it matter which graph friend choose? the does! That's due to the fact that each different types of graphs have pros and cons as soon as you use them. In order to most clearly demonstrate your data and your findings, you will have to learn exactly how to pick the best graph.

You are watching: Which of the following is an advantage to using graphs and diagrams

What are straight equations

Before we begin, you'll view that a many graphs map out linear equations. That's when you'll acquire a linear graph. You should understand some linear relationship instances in different forms, such together the slope-intercept type or the basic form, and you should have actually learned just how to solve straight equations v graphing.

hopeful and an unfavorable slope

Another point we'll have actually to conveniently revise are hopeful and an adverse slopes when you've gained data laid out in a straight fashion. You're usually able to read whether a steep is optimistic or negative from a graph. Once you've acquired a positive slope, it method your data is positively associated with every other. Once xxx increases, yyy will additionally increase. Conversely, if your graph has actually a an adverse slope, your data is negatively correlated. Once xxx increases, yyy decreases, and also vice versa.

A most times, your graphs will assist display whether there's a optimistic or negative correlation.

Different types of graphs

Bar graphs

When you've got data that has various categories, a bar graph is great for displaying your info. You're maybe to conveniently compare several data sets and also it's visually straightforward as soon as someone reads it.

However, an concern with a bar graph is that it have the right to only be provided with discrete data (data that only takes on specific values). That can likewise be misleading, since if friend organize a bar graph a particular way, it could emphasize a details effect also though that effect isn't actually that statistically relevant.

Other 보다 a conventional bar graph, there's something dubbed the double bar graph. Double bar graphs enable you to compare two sets of data across categories. You're able to make comparisons across intervals (similar to a continual bar graph). The course, over there are additionally disadvantages to bar graphs. Among the main concerns is that it's difficult to identify fractions or uncover percents in her data as soon as you've laid whatever out in twin bar graphs.

circle graphs

If you are working with data that use totality percentages, circle graphs will certainly be perfect because that you. An additional name for circle graphs space pie charts. Store in mind the the sum of the percents the you'll have actually in her circle graphs need to equal to 100%. Various other than the main advantage that one graphs are able to show total percentages for each classification that you're displaying, it's additionally visually appealing.

The flaw of circle graphs is the it's difficult to compare two sets that data v each other. The number data the you screen isn't an extremely exact. You should usually just use a one graph if girlfriend have in between 3-7 categories that you're comparing. Lastly, one graphs can only be provided with discrete data.

line graphs

Line graphs can provide a quick analysis of data. You're able to conveniently tell the range, minimum/maximum, as well as if there are any kind of gaps or clusters. This also way that the can conveniently observe transforms over a certain period of time. When illustration them, you're able come use specific values from her data.

So what are its disadvantages? Well, line graphs room generally an excellent only once you have actually under 50 data values. It likewise requires the the variety in her data not be as well big. Friend may have actually noticed the the heat graph isn't as visually appealing as several of the various other graphs we've explored together well.

Pictographs

Pictographs are visually appealing graphs that are ideal used with data that can be represented with symbols. It's rather easy to read and also can take care of a huge set of data well.

However, pictographs run right into a trouble when you're make the efforts to display partial icons. It's a very simplistic form of graph, for this reason you will certainly not be able to show more complex observations in data sets v them. Lastly, the really just works well through 2-6 categories.

Example problems

Question 1:

Jane measured the load of her kitten in ~ the finish of every month. She used a pictograph and also a line graph to display screen the data.

1a) In which 2 months walk the kitten grow at the same rate? i m sorry graph reflects this an ext clearly?

<1,2>,<2-3> has the same rate of growth. The line graph is much more clear because we can discover the rate merely by finding the steep of the line.

1b) in between which 2 months walk the kitten thrive the most? i beg your pardon graph reflects this more clearly?

<3,4> does since it has actually the steepest slope.

1c) offer one advantage and one disadvantage because that each month

Line graph:

Advantage: It's much better for seeing the rate clearly.

Disadvantage: It's harder to compare.

Pictograph:

Advantage: it is better for finding the weight.

Disadvantage: We room unable to watch the data between points.
