Graphs
Graphs often collect a set of data in a group of people. There are many kinds of graphs: pie charts (circle charts), bar graphs, line graphs, data tables, pictographs, flow charts, histograms, etc.

The Reliability of pie charts in newspaper articles?
The reliability of pie charts in a newspaper depends on the reliability of the data sources. If the sources of data are correct and the graph is constructed correctly, then the pie chart is reliable.
Show an example of a pictograph?
Here's a link. http://www.iss.k12.nc.us/schools/sharon/kaybrown/weather/pictograph1.GIF
What do line graphs and bar graphs have in common?
Bar graphs and line graphs are designed to show different values of two or more subjects. They both organize data. They both use an x-axis and a y-axis.
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable.
A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
What do you mean when you say a histogram is skewed to the right?
A right or positive skew means the data in the histogram will tail out to the right. See the related link figure 15.6 and it shows a right skew.
How can you use range when planning to draw a line graph?
You could use the range to select the scale for the axis.
The pie graph is used for what kind of data?
Any kind of data - nominal, ordinal or interval - provided you can group the data into a few categories. Ideally not more than seven, though in exceptional cases, up to ten may be used.
a triple bar graph is where you show thrree different things by different colors.go to google and type triple bar graph for a picture.
At the modal value(s).
54 or 54.0
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 the differences between line graph and line plot?
On a line graph, the points are connected by a line. Hence the name 'line graph". A line plot is, A line plot can be used as an initial record of discrete data values. The range determines a number line which is then plotted with X's for each data value.
In a line graph does 0 have to be in the y axle?
The y-axis (not axle) is the set of all points on the coordinate plane for which x = 0. So if you are looking for the point on the line for which x = 0 then it must, by definition, be on the y-axis.
What is the difference between double bar and double line graphs?
Double Bar graphs are usually used to show different amounts of different subjects and are depicted using "bars".
Double Line graphs are used to show fluctuations and changes in different subjects. They are presented with straight, curved or broken lines.
What is a disadvantage to using graphs and diagrams?
1. The information may be in a form that is too difficult to use.
2. They sometimes give you too much information.
What is the difference between a line graph and a scatter graph?
A line graph would be what you plot for a function. for example, y = X2. Plotting this will result in a continuous line.
A scatter graph will result from measuring a population or an experiment.
For example, if you plotted the weight vs height for your class members, you would have a scatter graph.
