Data plotted on a graph results in a line that slopes upward from left to right. This graph tells you that a)when one variable increases, the other variable decreases. or b) when one variable increases, the other variable increases?
what is the answer
Based on the information provided, when data plotted on a graph results in a line that slopes upward from left to right, it indicates that as one variable increases, the other variable also increases.
So the correct answer is b) when one variable increases, the other variable increases.
A line that slopes upward from left to right on a graph indicates a positive correlation between the variables. This means that as one variable increases, the other variable also increases. Therefore, the correct answer is b) when one variable increases, the other variable increases.
To understand this correlation, you can follow these steps:
1. Collect the data: Gather data for the two variables you want to analyze. For example, if you're examining the relationship between temperature and ice cream sales, collect data on different temperatures and the corresponding quantities of ice cream sold.
2. Plot the data: On a graph, label the x-axis with one variable and the y-axis with the other variable. Place a dot or marker on the graph for each data point, indicating the value of the variables at that point.
3. Analyze the slope: Look at how the plotted points are distributed on the graph. If they form a line that slopes upward from left to right, it indicates a positive correlation.
4. Interpret the correlation: Once you determine the correlation, you can draw conclusions. In this case, a positive correlation means that as the x-variable (e.g., temperature) increases, the y-variable (e.g., ice cream sales) also increases.
Remember that correlation does not necessarily imply causation. It only shows the relationship between the variables being studied.
