Graphs

To show the proportions of the whole, without actually indicating the values.

The distance covered between two points in time is the area under the graph between the two points.

If there are only a small number of components (3 to 8) to a total, then a pie chart is an effective way of showing the breakdown of the total into its components. A pie is not particularly useful if some of the components are very small or if there are a large number of components. A pie cannot be used if any of the components is negative.

The height of the column.

Yes, a circle graph and a pie chart are the same thing

Yes, any data set can be displayed using a histogram, as long as it represents original data, or data that does fall in a particular order.

Line graphs are often more clear to analyze, and are used for continuous data. bar graphs are used for just a certain amount of results, ones that don't continue.

When you are graphing some quantity, in many cases you will wind up with a curve that is shaped like a bell, in other words, the graph gradually rises, then rises more sharply, then flattens out and declines in a symmetrical pattern, the same way that it rose. This reflects the fact that a great many things have a normal range, and so the quantity of that item peaks in the normal range and then declines as you get either more or less than the peak, and furthermore, the pattern does tend to form that distinctive bell shape. You could, for example, do a chart of the annual income of American families. Some have very high income, some have very low income, and most fall in the intermediate range. But you could do the same thing with endless numbers of other topics. If you were to capture pigeons and make accurate measurements of the lengths of their beaks, and then graph the results, you would get a bell curve. You could graph the weight of pet cats, or the cost of sweaters, or the age of houses, and so forth. Most things will produce some kind of bell curve.

A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.

That would depend on the set of data. It would most likely be a dog.

A bar graph exhibits the relative sizes of quantities, by using bars of different length.

In statistics when comparing data

It is the graphical representation of a linear relationship between two variables.

In its most general form, the relationship is of the form

a1x1 + a2x2 + ... + anxn + c = 0 where x1, x2 etc are variables, and the as are constants. This equation would be a straight line in n-dimensional space.

In 2-dimensional space, and renaming the variables, you get

ax + by + c = 0 where x and y are the variables and a, b and c are constants.

This equation can be expressed in the form y = mx + d where m and d are constants. m is called the slope or gradient. For every increase of 1 unit in x, you will get an increase of m units in y. Also, d is called the intercept and it represents the value of y when x is 0.

put a horizontal one on its side :)

Continuous data

A histogram is a bar chart that only uses numbers.

The word "other" in the question implies that you already have some idea of what can be shown. Without knowledge of what you already have "on your list" it is impossible to say what is other.

Select any value for one of the variables in the graph and solve the equation to get the other variable.

It is called so because it is shaped like a pie. It is also called a circle chart.

3D pie charts are not a good idea because most people are not very good at adjusting for the perspective difference between the front and the back of the pie.
