line graph
when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.
It is very useful and interesting to be able to enter data for two variables, graph those points in a scatter plot, and then generate a line of best fit through those points. From the line of best fit, it is fairly simple to generate a linear equation. A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions.
so you know the relationship between the 2 variables
Correlation analysis is a type of statistical analysis used to measure the strength of the relationship between two variables. It is used to determine whether there is a cause-and-effect relationship between two variables or if one of the variables is simply related to the other. It is usually expressed as a correlation coefficient a number between -1 and 1. A positive correlation coefficient means that the variables move in the same direction while a negative correlation coefficient means they move in opposite directions.Regression analysis is a type of statistical analysis used to predict the value of one variable based on the value of another. This type of analysis is used to determine the relationship between two or more variables and to determine the direction strength and form of the relationship. Regression analysis is useful for predicting future values of the dependent variable given a set of independent variables.Correlation Analysis is used to measure the strength of the relationship between two variables.Regression Analysis is used to predict the value of one variable based on the value of another.
A pie chart is useful for between 3 and 7 or 8 segments. With more segments it becomes difficult to use. A pie chart is useful for looking at the breakdown, into parts, of a single total. It is not very good for comparing the breakdowns of two (or more) variables: for example, budgets headings for two years. This is because many people confuse the fact that a circle of double the radius would represent a quadrupling of the total. This quadratic relationship is often used to misrepresent data.

A regression graph is most useful for predicting dependent variables, as it shows the relationship between the independent and dependent variables, allowing for the prediction of future values.
i believe the answer is.... A strong OBSERVATION can be useful for making predictions

Time Series.
The number of electrons an element has determine the organization. This table helps in making predictions about how an element will chemically react.
Constant Variables
Ex Post Facto (also called Causal Comparative Research) is useful whenever: • We have two groups which differ on an independent variable and we want to test hypotheses about differences on one or more dependent variables OR • We have two groups which already differ on a dependent variable and we want to test hypotheses about differences on one or more independent variables
