The line of best fit for the data points with a positive correlation would have a positive slope. In a positive correlation, both the variables increase or decrease in a similar manner. How Can You Differentiate Between a Positive and Negative Correlation on a Scatter Plot? Plotting the variables on a scatter diagram is a systematic way to view the relationship between the variables and see if it's a positive or negative correlation. You can use a scatter plot when you have at least two variables that can be paired well together. Scatter plots help find the correlation within the data.

The collected data of the temperature and humidity can be presented in the form of a scatter plot. Refer to the table given below and indicate the method to find the humidity at a temperature of 60 degrees Fahrenheit. Observe the below scatter plot showing the number of birds on a tree versus time of the day.Įxample 2: The meteorological department has collected the following data about the temperature and humidity in their town. For example, the data for the number of birds on a tree at different times of the day does not show any correlation. Here the points are distributed randomly across the graph. Observe the below image of negative scatter plot depicting the amount of production of wheat against the respective price of wheat.Ī scatter plot with no clear increasing or decreasing trend in the values of the variables is said to have no correlation. The scatter plot for the relationship between the time spent studying for an examination and the marks scored can be referred to as having a positive correlation.Ī scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation. Based on the correlation, scatter plots can be classified as follows.Ī scatter plot with increasing values of both variables can be said to have a positive correlation.
