Question

A computer has found for a give set of values of x, y and z : rxy= 0.40,rxy=0.50 and rxy= 0.30

Answer 1

Explanation:

If r is significant and the scatter plot shows a linear trend, the line can be used to predict the value of y for values of x that are within the

Answer 2

Answer:

Yes, it is possible that these calculations are error-free. ​

Explanation:

• When one of the variables is connected to the other in some way, there is a correlation between the two. The most effective starting point is a scatterplot.
• A graph of the paired (x, y) sample data with a horizontal x-axis and a vertical y-axis is called a scatterplot (or scatter diagram). Each unique (x, y) pair is represented by a single point on the graph.
• the x1, x2 partial correlation coefficient, with x3 held constant. The symbol for this is r123.
• The line can be used to forecast the value of y for values of x that are within the range of significance if r is significant and the scatter plot has a linear trend.
