The greater the dispersion of the points plotted on the chart, the lower the degree of correlation between the variables. The degree to which the variables are related to one another is determined by how the points are distributed on the chart. It denotes that the variables are linked. Both variables, along with their respective values and data ranges, should be included in the table.Ģnd Step: Create a graph that shows the independent variable on the \(x\)-axis and the dependent variable on the \(y-\) axis.ģrd Step: Place a dot on the graph where the values of the two variables intersect.Ĥth Step: If there is a pattern, note it.

Practice Exam Questions on EMBIBE How to Plot a Scatter Diagram?īelow given are the steps to plot a scatter diagram:ġst Step: To plot the scatter diagram, first record the data in a tabular format, either in Excel or on paper by hand. You can use scatter plots as a marketer to analyse keyword data in SEM marketing. When data is plotted, the resulting plot is skewed. The independent variable is represented on the \(x-\) axis, while the dependent variable is represented on the \(y-\) axis. Values on Axis: To restore any of the values to their default states, click on the reset button.A scatter plot (also known as an \(x-y\) graph) is a type of chart used to express the relationship between two variables or data points.Īlong the \(x\) and \(y-\) axis, two data points are plotted.To change the default minimum, maximum or interval values on the axis, type in the new values, and click outside the text boxes to apply the new values. Click outside the text box to apply the new value. Title: Select the checkbox to display the axis title.Logarithmic: Displays using orders of magnitude.Select the orientation of these labels: Horizontal: (Default), Diagonal or Vertical. Value Labels: Specify whether to show or hide labels indicating the values of each point (circle).If you are using the Point value, drag each side of the slider to determine the relative minimum and maximum circle sizes. If you are not using a Point value, the slider will change the size of all the points on the map. Marker Size: Change the size of the circles.Legend: Specify whether to show or hide the Legend, and select its position.It must be numeric data.įine tune the appearance of the SCATTER CHART widget, using the following tools. In the Size panel, select the field that determines the size of the circle. If you select numeric data, then the point color is a gradient where the highest value is the darkest color and the lowest value is the lightest color. Select a field by which to color the fields in the chart. Each member is represented by a different color. If you select descriptive data, then the points in the chart are grouped into the members of the field. You can only add a point if either the X-Axis or the Y-Axis was defined to represent numeric data.īreak by/ Color: Select a field by which to break (group) the fields in the chart. These fields must be descriptive data (not numeric data). The point area determines the field to be scattered across the chart as circles one point (circle) appears on the chart for each member of this field. In the Point panel, click Add + to select the point field. Alternatively, descriptive data is also supported. Typically, the Y‑Axis of a Scatter Chart is used to represent numeric data. In the Y-Axis panel, click Add + to select the field whose values will be placed on the Y-Axis. Alternatively, Descriptive data is also supported. Typically, the X-Axis of a Scatter Chart is used to represent numeric data. In the X-Axis panel, click Add + to select the field whose values will be placed on the X-Axis.
If used, the circle size is relative to their value. If omitted, all scatter points are equal in size. Size: An optional field represented by the size of the circles. The maximum amount of data points is 500.
