How should one interpret data presented in a graph?
Answer: To interpret a graph or chart, read the title, look at the key, read the labels. Then study the graph to understand what it shows.
Which chart should I use?
Bar charts are good for comparisons, while line charts work better for trends. Scatter plot charts are good for relationships and distributions, but pie charts should be used only for simple compositions — never for comparisons or distributions. Andrew Abela that should help you pick the right chart for your data type.
What type of graph is best to compare two sets of data 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.
What is the y axis in a bar graph?
In most bar graphs, like the one above, the y-axis runs vertically (us and down). Sometimes bar graphs are made so that the bars are sideways like in the graph to the left. Then the y-axis is horizontal (flat). Typically, the y-axis has numbers for the amount of stuff being measured.
What is a disadvantage of a line graph?
What Are the Disadvantages of A Line Graph? 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 made of total figures such as values of total rainfall in a month.
What is the difference between a bar chart and a line graph?
Bar graphs show data with blocks of different lengths, whereas line graphs show a series of points connected by straight lines.
What are three important features of charts and graphs?
Answer: The title tells us what the subject of the chart or graph is. The vertical axis tells us what is being measured. And the horizontal axis tells us the units of measurement represented.
What would be the best use of a line graph?
Line graphs are used when smaller changes exist.. Line graphs can also be utilized to compare changes over the same period of time for more than one group. So, a line graph features showing trends, and the best use of a line graph is data that changes over time.
What is the advantage of using multiple lines in a line graph?
Multiple line graphs have space-saving characteristics over a comparable grouped bar graph. Because the data values are marked by small marks (points) and not bars, they do not have to be offset from each other (only when data values are very dense does this become a problem).
