There are numerous ways in which a misleading graph may be constructed.Excessive usage. The use of graphs where they are not needed can lead to unnecessary confusion/interpretation. ... Biased labeling. ... Pie chart. ... Improper scaling. ... Truncated graph. ... Axis changes. ... No scale. ... Improper intervals or units.More items...
A pie chart, sometimes called a circle chart, is a way of summarizing a set of nominal data or displaying the different values of a given variable (e.g. percentage distribution). This type of chart is a circle divided into a series of segments.
A line graph shows data from one source, while a scatter plot shows data from many sources.
What are some ways in which graphs can mislead or misinform readers? We consider graphs deceptive if they purposely create an incorrect impression. The most common graphical misrepresentations of data involve the scale of the graph, an inconsistent scale, or a misplaced origin.
A bar graph is used for displaying categories (or classes) of qualitative variables while histograms are used to display groupings of similar data values for quantitative data.
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.
Scatter charts show the relationship between two variables. To construct a scatter chart, we need observations that consist of pairs of variables.
Data visualization presents UML Class diagrams. Which type of chart is best to show a persons' weight over time? Line chart.
Answer and Explanation: Pie charts, also called pie graphs, are used to show how the parts of a whole compare to each other in size.
Histograms visualize quantitative data or numerical data, whereas bar charts display categorical variables. In most instances, the numerical data in a histogram will be continuous (having infinite values). Attempting to display all possible values of a continuous variable along an axis would be foolish.
Two graphs that are used to display categorical data are pie charts and bar graphs.
Scatter plots are similar to line graphs in that they start with mapping quantitative data points. The difference is that with a scatter plot, the decision is made that the individual points should not be connected directly together with a line but, instead express a trend.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
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 type of data can be displayed in a circle graph? Bar graph? On a circle graph, you show parts of a fixed whole, percentages. With that, you can display data such as the amount of certain substances in a liquid.
Histograms visualize quantitative data or numerical data, whereas bar charts display categorical variables. In most instances, the numerical data in a histogram will be continuous (having infinite values). Attempting to display all possible values of a continuous variable along an axis would be foolish.

Rachel wants her graph to emphasize the relation of each city's precipitation to each other city's at each point in time. What kind of graph would be appropriate?
There appear to be 50% more sales of horror books than cookbooks, but there are really only about 20% more.
A line graph is a smooth curve, while a scatter plot can have jumps or gaps.
The data should be presented in increasing or decreasing order.
A line graph uses both the x- and y-axes, while a scatter plot only uses the y-axis.
B - Bar Graph 1 is misleading because the vertical axis does not start and 0 and the scale for the graph is 0.25 instead of 1.
D - There appear to be 25% more sales of horror books than cookbooks, but there are really only about 2% more.
A - A line graph presents continuous and linked data, while a scatter plot presents unlinked data.
Abger Electronics, a retail store, restructures its employees' schedules every six months. The employees are asked for their shift preferences, and the schedules are rearranged according to these preferences. When there is a conflict, those with the best total sales over the past six months are given priority. The following graph and table show the most recent sales records and employee preferences, respectively.
In order to make the data more readable, Natasha has decided to put it into a graph. Which of the following graphs accurately matches the information in the table?
Walter is planning a trip to Morocco. He is trying to decide which cities he would like to visit while he is there. The table below shows some possible cities Walter could visit, along with the amount of money he expects to spend on food, lodging, travel, and similar expenses for each city.
C - It is not always possible to calculate theoretical probability in complex situations, but experimental probability can be calculated any time experiments can be run.
You determined that Clancy's economic profit in the piano business is $1,000. On the other hand, his economic profit as a paralegal would equal his salary plus revenue he would earn from renting out his building minus his implicit costs (the accounting profit he would earn in the piano business), for a total of: $22,000+$13,000−$36,000=−$1,000$22,000+$13,000−$36,000=−$1,000.
Use the orange points (square symbol ) to plot Larry's total cost curve on the following graph using the quantities from the preceding table.
Clancy's explicit costs of running the piano business include the wholesale cost of $426,000 and wages and utility costs of $264,000. His implicit costs are the forgone salary income of $22,000 that he could have earned as a paralegal and the forgone rental income of $13,000. Therefore, his total costs of running the piano business ($725,000) are less than the revenue he receives from selling pianos ($726,000).
The slope of the production function measures the change in output for each additional unit of labor input, known as the marginal product of labor. From the graph, you can see that the production function becomes flatter as the number of workers increases, representing the property of diminishing marginal product of labor.
The orange point on ATC3ATC3 indicates the firm's current output level in the short run (Q4Q4).
Total revenue is equal to price times quantity. Therefore, the total revenue curve is an increasing line with a slope of $10 per unit.
Clancy should stay in the piano business because he would earn less economic profit (total revenue minus all explicit and implicit costs) if he were to rent out the space and work as a paralegal.
