Dot Plots
Plotting is an important part of statistics as a pictorial representation of data gives a clear idea of data. Dot plots are a visualization of data which can give information about the frequency distribution of the data. A dot plot can give an overall view of the data based on if it is skewed or not.

Dot PlotEdit
A dot plot is a way to present numerical data. A dot plot is a number line with dot placed on it corresponding to their value. The intervals between each number stays the same.

Dot Plot Math Definition

A Line plot can be defined as a graph that displays data as points or check marks above a number line, showing the frequency of each value. A cobweb plot, or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions, such as the logistic map. Using a cobweb plot, it is possible to infer the long term status of an initial condition under repeated application of a map.

Dot plots can be used to display various types of information. Figure 1 uses a dot plot to display the number of M & M's of each color found in a bag of M & M's. Each dot represents a single M & M. From the figure, you can see that there were 3 blue M & M's, 19 brown M & M's, etc.

A ~ is as shown in the figure.
The frequency of the data points is represented by the dots.

~. See: line plot.
Dilation. A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distances from the center by a common scale factor.

A ~ is a way of summarising data, often used in exploratory data analysis to illustrate the major features of the distribution of the data in a convenient form.

Dot pots are similar to single-valued histograms, but rather than placing rectangles above each particular value, a ~ just places the required number of dots above each value. Looking at our example again with the number of children, the plot would look something like this:

A ~ is a hybrid between a histogram and a stem and leaf plot. Each quantitative data value becomes a dot or point that is placed above the appropriate class values.

~
A graph for displaying the distribution of a numerical variable in which each dot represents a value of the variable.
For a whole-number variable, if a value occurs more than once, the dots are placed one above the other so that the height of the column of dots represents the frequency for that value.

~
A form of a histogram for which an observation with a value within a certain range is plotted as a dot a fixed interval above the previous dot in that same range. Useful for small numbers of observations.

One of the most basic ways to display statistical data is a line plot (or ~ ). This is used for surveys of small numbers of people, or to show a distribution of data about a small set.
Example:
Suppose you count the number of students in each classroom in your school.

This graph includes the addition of a ~. The ~ is the collection of points along the left y-axis. These are the values of the residuals. The purpose of the ~ is to provide an indication the distribution of the residuals.

Data Plots Definition Math

A line plot, sometimes called a ~, helps us get a better understanding of a small number of observations. A line represents the variable you are interested in and the values of the variable are labels on the line. Each observation is marked as a point above the line.

A way to organize data along a number line where the X (or other symbols) above a number represent how often each value is mentioned. A line plot made with dots is sometimes referred to as a ~.
