based on the ordered pairs in the data below, state whether there is no correlation, a weak correlation or a strong correlation. If there is indeed correlations, determine whether the correlation is negative or positive. x: 1 2 3 4 5 6 7 8 9 y:300,293,276,270,250,249,233,221,219
Question
Answer:
Answer:The data is a strong correlation and correlation is negative.Step-by-step explanation:Given : Based on the ordered pairs in the data below:x: 1 2 3 4 5 6 7 8 9
y: 300 293 276 270 250 249 233 221 219 To find : Whether there is no correlation, a weak correlation or a strong correlation. If there is indeed correlations, determine whether the correlation is negative or positive. Solution : On plotting the scatter plot on the basis of table of values,We see that the relation is a strong correlation since we can find a relationship between variable x and y.As the points will lie above or below the curve which is formed by connecting some points of the scatter plot and are not scattered away.So, The data is a strong correlation.Also the graph is a negative correlation since with the increasing value of x the y-value decreases.
So, The correlation is negative.
