Time Series.
To make predictions about dependent variables, common graphs used include scatter plots, which show relationships between two variables, and line graphs, which can illustrate trends over time. Regression analysis often employs these graphs to visualize the relationship and predict outcomes. Additionally, bar graphs can be useful for comparing categorical data, while histograms help understand the distribution of a continuous variable.
Linear equations can be used for forecasting by establishing a relationship between a dependent variable (such as sales or demand) and one or more independent variables (like time, price, or marketing spend). By analyzing historical data, you can create a linear regression model to predict future values based on this relationship. Once the equation is formulated, you can input future values of the independent variables to estimate the dependent variable, aiding in decision-making and planning. This method is particularly useful for identifying trends and making data-driven forecasts.
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2

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
Predictions
when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.

The number of electrons an element has determine the organization. This table helps in making predictions about how an element will chemically react.
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
