What is the pictorial presentation of the relationship between variables?
A scatter diagram. A line diagram will not be as good at showing a relationship that is non-linear (not a straight line).
Is cellphone number a qualitative variables?
No, it is quantitative.
What to use If you want to show the relationship between two sets of data?
The answer depends on what sort of variables the data are (qualitative, quantitative-discrete, quantitative-continuous are; the nature of the relationship (if any) between the data sets; how much information you wish the graph to convey and how much you would prefer to describe in the accompanying text.
How to graph independent and dependent variables?
The answer depends on the nature of the variables: for a start, whether they are qualitative or quantitative.
What does the line on a speed or time graph show?
The shape and slope of the line on a graph illustrates the qualitative and quantitative relationship between the variables plotted on the axes of the graph. Sadly, there is no such graph as a "speed or time" one.
What measures the strength of the linear relationship between two quantitative variables?
The coefficient of determination, otherwise known as the r^2 value, measures the strength of the linear relationship between two quantitative variables. An r^2 value of 1 indicates a complete linear relationship while a value of 0 means there is no relationship.
What graphical technique should be used to display a correlation?
A scatter plot is a graphical technique commonly used to display correlations between two variables. It allows you to visually observe the relationship between the variables and assess the strength and direction of the correlation.
What is the meaning of quantitative variables?
They are variables that can take quantitative - as opposed to qualitative values. For example, the colour of peoples' eyes is a qualitative variable, but their age or shoe size are quantitative variables.
What is a graphical relationship?
A graphical relationship refers to the visual representation of the connection or correlation between two or more variables through graphs or charts. It helps to illustrate patterns, trends, or associations between the data points for easier interpretation and analysis.
What is the pictorial presentation of the relationship between variables?
A scatter diagram. A line diagram will not be as good at showing a relationship that is non-linear (not a straight line).
What are the two way to determine if the relationship between two quantities are proportional?
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
What are the benefits of graphical representation of equations?
Graphing an equation allows you to visualize the relationship between variables and predict values of one relative to the other
Quantitative variables can be separated into what two types?
nominal and ordinal is wrong; those are the two types of qualitative variables. Ratio and interval are the two types of quantitative variables.
What is a popular form of summary many sociologists utilize to quickly and clearly show a relationship between two variables?
Sociologists often use scatter plots to visually represent the relationship between two variables. This graphical tool helps quickly identify patterns and trends in the data, showing the strength and direction of the relationship between the variables.
Is cellphone number a qualitative variables?
No, it is quantitative.
A correlation of zero between two quantitative variables means that?
It means there is no discernable relationship between the two variables. Knowing one variable does not give you any help in working out the other. They are independent of each other.
What is the meaning of quantitation?
They are variables that can take quantitative - as opposed to qualitative values. For example, the colour of peoples' eyes is a qualitative variable, but their age or shoe size are quantitative variables.
