Are Line graphs are good at showing changes over time?

Are graphs good at showing changes and relationships?

Yes.

Why would you use a pie graph instead of a line graph?

pie graphs show volume and are good for showing the relationship of size. line graphs are good for showing trends which can lead to predictions.

What are pie graphs good for?

Pie graphs are good for showing a percent of something.

What are the uses of a bar graph?

Bar graphs can be used to easily compare data that are relevant to one another. An example is numbers from a science experiment. Bar graphs are good at showing quantities rather than change that is shown on a line graph.

What graphs are used in finding trends in data?

Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.

What type of graph would you use to display various types of data?

. . . a Line graph.Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.. . . a Pie Chart.Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.. . . 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.. . . an Area Graph.Area graphs are very similar to line graphs. They can be used to track changes over time for one or more groups. Area graphs are good to use when you are tracking the changes in two or more related groups that make up one whole category (for example public and private groups).. . . an X-Y Plot.X-Y plots are used to determine relationships between the two different things. The x-axis is used to measure one event (or variable) and the y-axis is used to measure the other. If both variables increase at the same time, they have a positive relationship. If one variable decreases while the other increases, they have a negative relationship. Sometimes the variables don't follow any pattern and have no relationship.:)

What is the difference between line graphs and bar graphs?

one is a line and the other one are bars^^^that is a silly answer.^^^^that is a funny answer!the real answer is that line graphs are better at demonstrating something when both of your quantities or units involved are NUMBERS while graphs work better when one is words. for example, a bar graph would be good for "how much money you make per week" because the week side would be words however, "how much money you make per HOUR" would be good as a line graph because hours are also numbers. Hope that helps!A line bar shows the different amounts between things. A circle graph shows the percentages of things.

What are bar graph not good for?

bar graphs are usually used for results that have a variable whose units are described in words and the other variable whose units are described in numbers such as the y axis, the vertical line, is the number of people and the x axis, the line going horizontal, is the colour of eyes. bar graphs are not useful for the y axis and x axis both units are in numbers. these are mainly used for line graphs

What are a graphs advantages?

There are a few good things about graphs. Graphs help gather data making it easier for people to short things out.

Can a graph be good at showing changes and relationships?

sometimes I guess but they would be weird if you were trying to show them to your partner.

What is the pictorial presentation of the relationship between variables?

A scatter diagram. A line diagram will not be as good at showing a relationship that is non-linear (not a straight line).
