A scatter diagram (Also known as scatter plot, scatter graph, and correlation chart) is a tool for analyzing relationships between two variables for determining how closely the two variables are related. Statistics - Stem and Leaf Plot, Stemplots are similar to histogram with the difference that in histogram, bars are used to compare data and in case of stemplots leaves represents actual number Introduction: Besides textual and tabular presentations of statistical data, the third and perhaps the most attractive and commonly used popular modem device to exhibit any data in a systematic manner is to represent them with suitable and appropriate diagrams and pictures. It is shown in the form of rectangles spaced out with equal spaces between them and having equal width. You should be able to read and draw the following: 1. Dot Plots. By using this method, one can estimate both the magnitude and significance of causal connections between variables. If we have two or more sets, we can use a Venn diagram to show the logical relationship among these sets as well as the cardinality of those sets. It is the statistics graph that is used for a certain kind of paired data. Statistical diagrams covers: data collection; extracting data from tables, mileage charts and timetables; data presentation using stem and leaf diagrams, line graphs, tally charts, pie charts and frequency tables; the statistical measures of mean, mode, median and range; plotting scatter diagrams; lines of best fit and Line diagram in statistics : When the data vary over time, we take recourse to line diagram. The plotted points are then joined successively by line segments and the resulting chart is known as line . The statistical charts are also known as pictographs. They are useful for highlighting clusters, gaps, skews in distribution, and outliers. The following example illustrates how to use a tree diagram. The circles or ovals represent events. Time-Series Graphs.

A tree diagram is a special type of graph used to determine the outcomes of an experiment. Seven types of graphs are commonly used in statistics. Ideally, one variable is plotted on the horizontal axis, while the other variable is plotted on the vertical axis.

First, we will denote a win by W and a loss by L. The first event is the first match. Statistics allows you to understand a subject much more deeply. If the variables are correlated, the points will fall along the line or curve. Range is used as a measure of dispersion when variations in the value of the variable are not much. Tree diagrams can make some probability problems easier to visualize and solve. 2 . 1. The statistical data in statistics is shown by charts, diagrams, and graphs for getting quick information.Charts and graphs of statistical data are catchy and time saver for collecting the information. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. You will learn about calculating the chance that an event will occur using various methods such as tree and Venn diagrams and conditional and mutually exclusive events. When the data vary over time, we take recourse to line diagram. A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items.
