What is the method to draw a scatter plot for a given data set?

To draw a scatter plot, plot each pair of data points on a graph with an x-axis and y-axis.

First, gather your data set, which should consist of pairs of values. These pairs are usually written as (x, y), where 'x' is the value on the horizontal axis (x-axis) and 'y' is the value on the vertical axis (y-axis). For example, if you have data on the number of hours studied and the corresponding test scores, 'hours studied' could be your x-values and 'test scores' your y-values.

Next, draw your axes on graph paper or using graphing software. Label the x-axis with the variable that represents your x-values and the y-axis with the variable that represents your y-values. Make sure to include a scale on both axes that covers the range of your data points.

Now, plot each pair of data points on the graph. For each pair (x, y), find the position on the x-axis that corresponds to the x-value and the position on the y-axis that corresponds to the y-value. Place a dot where these two positions meet on the graph.

After plotting all the points, you can start to analyse the scatter plot. Look for any patterns or trends. For example, if the points tend to rise from left to right, this suggests a positive correlation between the variables. If they fall from left to right, this suggests a negative correlation. If the points are scattered randomly, there may be no correlation.

Scatter plots are useful for visualising the relationship between two variables and can help you identify trends, clusters, and outliers in your data.
