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.

How are bar graphs and picture graphs alike?
Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.
What is the purpose of mean absolute deviation?
Various answers to this question are possible.
The mean absolute deviation (MAD) is a measure of the dispersion or spread of a sample or a population. So one of its purposes is as a measure.
As such it's an alternative to the standard deviation that is said to be more robust in the sense that the sample MAD can be used to provide more accurate estimates of the population dispersion because it is less sensitive to outliers.
Beyond this, some distributions that have no standard deviations do have MADs; for example, the Cauchy. This means that the dispersions of virtually all distributions can be compared in terms of their MADs.

A graph that shows information as parts of a circle is called what?
A graph that shows information as parts of a circle is called a pie chart.
HOW are quartiles helpful in describing data?
They are a simple measure of the spread of the data, which is not affected by extreme values.
Graph is a pictorial or graphical representation between or among different things. Graph helps an individual in taking quick actions.
Your question makes no sense, you cannot "reinstall" programming languages (or vitamines, or letters, or Roman numbers)
What does a graph of data make easier to understand then a table of data?
It shows how one set of data relates to the others, and to itself, it is easier to see trends when the data is graphed.
A histogram is a display of statistical information that uses rectangles to show the frequency of data items in a successive numerical intervals of equal size. In most histograms the independent variable is plotted along the horizontal axis and the dependant variable is plotted along the vertical axis. The data appears as colored or shaded rectangles of variable area . Some histograms are presented with the independent variable in the vertical axis and the dependent variable in the horizontal axis.
In Photography
Histograms are used to indicate the range of gray tones from absolute black to absolute white that are captured in a photograph. The tone axis typically runs horizontally from left to right. The number of tones indicated can vary. Absolute black is at one end and absolute white is at the other end. The tone in the middle will be what is called "Middle Gray" in photographic terms.
The height of the bars indicates the amount of each tone that appears in the scene photographed. A very contrasty photo would have a histogram that looks like a valley between two very high peaks on either end. The bars on the White end and the bars on the black end would be very tall and the bars in the middle would be very low. A good goal would be to have a relatively good distribution of tones across the range from black through middle gray to white. It does not need to show a flat profile - in fact it shouldn't.

What does bar mean as in state bar for lawyers?
In the phrase "state bar," the word "bar" is referring to the body of lawyers who are qualified to practice law in that particular state/jurisdiction.
The bar is also a railing found in a courtroom which separates people conducting court related business, i.e. lawyers, judges, court personnel, witnesses, parties to a case, etc., from observers. The phrase "passing the bar" refers, not only to passing the bar exam, but also to a rite of passage - you transition from an observer to a lawyer by passing through the bar (the railing) during your swearing in ceremony (if this is part of your ceremony).
The BAR Association is an entitlement given to lawyers and judges who make an oath to the British Accredidation Registry.
Why did the student draw a bar chart rather than a line graph?
Your best chance of getting the correct answer is to ask the student who drew the chart.
The type of chart/graph that is best drawn depends upon the data being represented:
If the chart is being used to show how data represents a fraction of a whole, a Pie chart would be used.
If the chart is of discrete data, eg shoe sizes, a bar chart would be used.
If the chart is of continuous data, eg the height of people, a line chart would be used.
A pictogram is a version of the bar chart with the bars split up into icons which represent some kind of unit; eg for shoe sales of different styles a shop could use a shoe icon to represent 5 shoes with parts of a shoe icon representing 1-4 shoes sold.
In business which of the bar chart and line graph is used depends upon what sort of information is required to be shown and to whom*. For factual information about different items a bar chart is often used (eg how much is sales per month), but if a trend is required a line graph can be used (eg how is sales per month changing).
* The "to whom" bit is often the deciding factor - the choice of chart and how it is drawn can be used to great effect to enhance or hide certain aspects of the data.
Where can you find a chart or graph that shows the popularity of different sports?
look it up on answers.com
Answer:Whatever you found could be the subject of great controversy anyway, as there are quite widely differing figures on many of these claims concerning inter-country "popularity" of various sports, and who, even, engages the various sports within certain of these countries.
I have even seen claims that volleyball was the most popular sport in the world! Yet it ranks No 1 in very few countries.
Of the various 'figures' that we do have, many are highly unreliable.
However, the great consensus of worldwide opinion on this subject, states that association football [soccer] is by far the most played and most popular.
From there, opinions of those that follow soccer in popularity vary greatly.
When looking for a mathematical relationship between two variables use?
line graph or a scatter plot.
It's a circle that kind of looks like a pizza cut into pieces. Usually, the pieces are labeled as something (usually you compare things with a circle graph) and normally have percents along with the label. I'm sorry, I explained it the best way I could. If you have any questions, please e-mail me. To learn more about a circle graph; Also known as pie graph, check this out!
http://www.fedstats.gov/kids/mapstats/sconcepts_pie.html < Copy and paste into your broswer
This shows you how a pie/circle graph looks and also tells you what its used for.
A quick copy and paste from the site if your too lazy to do all of that.
"A circle graph or pie graph is used to show how a part of something relates to the whole.
This kind of graph is needed to show percentages effectively."

In graph theory, a circle graph is a graph whose vertices can be associated with chords of a circle such that two vertices are adjacent if and only if the corresponding chords in the circle intersect. In other words, a circle graph is the intersection graph of a set of chords of a circle.
What are 3 world events between 428 B.C. - 347 B.C.?
Plato was born in 428 B.C. and died in 347 B.C. so that's got to count for two! :P
If two bacteria cultures were plotted on semi graph paper for doubling time what would it look like?
It is not possible to answer the question since there is no such thing as a "semi graph paper"!
What are ripping bars used for?
A ripping bar is primarly used for extracting nails from used lumber, or to separate pieces of wood that are nailed together.
What is the history of The Line of Demarcation?
Spain and Portugal agreed on the Line of Demacration in 1494.
