This correlation would probably be considered moderate negative correlation. Scroll down the page for more examples and solutions using scatter graphs and correlations. The following diagram shows some examples of scatter graphs and correlations. It looks a little stronger than the previous scatter plot and the trend looks more obvious. Examples, solutions, and videos to help GCSE Maths students learn about scatter graphs and correlations. ![]() Graph 2.5.4: Scatter Plot of Life Expectancy versus Fertility Rate for All Countries in 2013Īgain, there is a downward trend. Let’s see what the scatter plot looks like with data from all countries in 2013 ("World health rankings," 2013). ![]() The trend is not strong which could be due to not having enough data or this could represent the actual relationship between these two variables. What this says is that as fertility rate increases, life expectancy decreases. Answer the given questions about this table on your answer sheet. The coaches of a group of debate teams answered a survey about hours of debate, team practice and. The table below shows the sales for a flower company for the years 2007 through 2012. With a variety of reasonable choices, students will estimate the correct r value and interpret positive and negative slope, as well as the strength or weakness of the correlation coefficient of a linear fit. Algebra Worksheet: Scatter Plots and Line of Best Fit. Graph 2.5.3: Scatter Plot of Life Expectancy versus Fertility Rateįrom the graph, you can see that there is somewhat of a downward trend, but it is not prominent. Our engaging worksheet is designed to match scatter plots with the correct correlation coefficient. 1 There is a negative correlation between the number of hours a student watches television and his or her social studies test score. Note: Always start the vertical axis at zero to avoid exaggeration of the data. The vertical axis needs to encompass the numbers 70.8 to 81.9, so have it range from zero to 90, and have tick marks every 10 units. Based on the correlation, scatter plots can be classified as follows. A scatter plot is a graph that shows the relationship, if any relationship. The horizontal axis needs to encompass 1.1 to 3.4, so have it range from zero to four, with tick marks every one unit. In this case, it seems to make more sense to predict what the life expectancy is doing based on fertility rate, so choose life expectancy to be the dependent variable and fertility rate to be the independent variable. Sometimes it is obvious which variable is which, and in some case it does not seem to be obvious. To make the scatter plot, you have to decide which variable is the independent variable and which one is the dependent variable.
