Thank you so much ceil phantomhive and Jess :]
When two variables are said to be negatively correlated, it means that there is an inverse relationship between them. In other words, as one variable increases, the other variable tends to decrease, and vice versa.
To understand whether two variables are negatively correlated, you can follow these steps:
1. Gather data: Collect data for the two variables of interest. For example, if you want to determine the correlation between studying hours and exam scores, you would need to gather information on the number of hours students study and their corresponding exam scores.
2. Plot scatter plot: Plot the data on a scatter plot, with one variable on the x-axis and the other on the y-axis. Each data point represents the value of both variables in a specific instance.
3. Observe the overall pattern: Look at the general pattern of the scatter plot. If the points on the plot tend to form a downward sloping line or cluster around a line with a negative slope, this suggests a negative correlation.
4. Calculate correlation coefficient: To quantify the strength and direction of the correlation, you can calculate the correlation coefficient, often denoted as "r." The correlation coefficient is a numerical value between -1 and 1. If the correlation coefficient is close to -1, it indicates a strong negative correlation.
Keep in mind that correlation does not imply causation. Even if two variables are negatively correlated, it does not necessarily mean that one variable is causing the change in the other variable. It simply shows that changes in one variable tend to be associated with changes in the other variable in the opposite direction.
