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.
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.
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.
Scatter charts show the relationship between two variables. To construct a scatter chart, we need observations that consist of pairs of variables.
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.
A relative frequency histogram has the same shape and the same horizontal scale as the corresponding frequency histogram. The difference is that the vertical scale measures the relative frequencies.
The correct answer is (C). Both histograms are mirror images around their center, so both are symmetric. With bar charts, the labels on the X axis are categorical; with histograms, the labels are quantitative. Because these charts were described in the problem statement as histograms, their labels are quantitative.
Terms in this set (6) How is a Pareto chart different from a standard vertical bar graph? The bars are positioned in order of decreasing height with the tallest bar on the left. a vertical line can be drawn through the middle of the graph of the distribution and the resulting halves are approximately mirror images.
Misleading Graphs in Real Life: Overview The “classic” types of misleading graphs include cases where: The Vertical scale is too big or too small, or skips numbers, or doesn't start at zero. The graph isn't labeled properly.
Two graphs that are used to display categorical data are pie charts and bar graphs.

scatter plot. a graph with points plotted to show a possible relationship between two sets of data. correlation.
Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.
Terms in this set (5) Scatter plots depict the results of gathering data on two variables; the line of best fit shows whether these two variables appear to be correlated. a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
-A scatterplot is a graph of paired (x,y) quantitative data. it provides a visual image of the data plotted as points, which helps show any patterns in the data. -A scatterplot is a graph of paired (x, y) qualitative data. It provides an organized display of the data, which helps show patterns in the data.

There appear to be 50% more sales of horror books than cookbooks, but there are really only about 20% more.
The data should be presented in increasing or decreasing order.
A line graph is a smooth curve, while a scatter plot can have jumps or gaps.
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?
A line graph uses both the x- and y-axes, while a scatter plot only uses the y-axis.
