Correlation
* * * * *
That is simply not true. Consider the coordinates of a circle. There is obviously a very strong relationship between the x coordinate and the y coordinate. But the correlation is not just small, but 0.
The correlation between two variables is a measure of the linear relationship between them. But there can be non-linear relationships which will not necessarily be reflected by any correlation.

Explain why bar graphs are useful for comparing data?
so you know the relationship between the 2 variables
A relationship between two variables or sets of data is called what?
Some people will give the answer "correlation". But that is not correct for the following reason: Consider the coordinates of a circle. There is obviously a very strong relationship between the x coordinate and the y coordinate. The correlation between the two is not just small, but 0. The correlation between two variables is a measure of the linear relationship between them. But there can be non-linear relationships which will not necessarily be reflected by any correlation.
Which of the following would let you show a relationship between two variables where each piece of data is connected to all the others?
Line graph
Why is it a good idea to make a graph of the data in the data table?
Viewing the data is an easy way to see some of their characteristics such as trends, seasonality, outliers, relationship between variables (linear, quadratic, power etc).
What do you call a measure of the strength and direction of the relationship between two variables or data sets?
A measure of association. You might be thinking of the correlation coefficient in particular.
What is a relationship between two variables or sets of data is called what?
Correlation
A diagram that tells how two variables are related is called what?
A diagram that shows how two variables are related is called a "scatter plot." It is a visual representation of the relationship between the two variables, often used to identify patterns or trends in the data.
What is the purpose of graphing data?
graph is a quick picture of relationship between two variables
What is the best way to represent data that compares the relationship between two variables?
A scatter plot.

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.
What is an explanation of the data that tells what relationship exists between the variable and the investigation called?
The explanation of data is called a theory.
Would let you show a relationship between two variables where each piece of data is connected to all the others?
Line Graph
What is correlational survey?
Correlational surveys involve measuring the relationship between two or more variables without manipulating them. By collecting data on these variables from a sample of participants, researchers can determine the extent to which changes in one variable are associated with changes in another, providing insight into potential patterns or connections between the variables.
What are the types of variables according to functional relationship?
The types of variables according to functional relationship are independent variables and dependent variables. Independent variables are inputs that are manipulated or controlled in an experiment, while dependent variables are the outputs that are affected by changes in the independent variables.
