Question

? canvas.cwu.edu information- Born Primitive- Checkout a) Does there appear to be a positive, negative, or no relationship? How can you tell? any evidence of a non-linear relationship? Why or why not, and what effect will this b) Is there have on the correlation coefficient (in other words, why does this matter)? o) Is there any evidence of issues such as heteroscedasticity or outliers? Why or why not, and what effect will they likely have if they're there? d) Roughly, what range would you expect r to be in? Why? (You should explain what r is on at least your first answer). ) Given all of your answers above, how accurate would you expect to be in predicting future Y scores based on X (i.e., would you expect the Standard Error of Estimation to be high, low, or moderate)? If you have said that there is no relationship, what would the Standard Error of Estimation be equal to (don't need to calculate a value here - recall that there is an upper limit to the SEoE)

Explanation / Answer

a) There is no any relationship between X and Y. Since there is no any pattern in the plot.

b) There is no any non linear relationship in the data. Because data is spare randomly, we have not seen any pattern in data.

c) Outlier is not present in the data.

d) The range of r2 is 0 to 0.4

e) The future obervation is estimated as average of given y data. beacase there is no any relationship between X and Y.
