Problem 6E

PROBLEM 6E

The following 54 pairs of data give, for Old Faithful geyser, the duration in minutes of an eruption and the time in minutes until the next eruption:

(a) Calculate the correlation coefficient, and construct a scatterplot, of these data.

(b) To estimate the distribution of the correlation coefficient, R, resample 500 samples of size 54 from the empirical distribution, and for each sample, calculate the value of R.

(c) Construct a histogram of these 500 observations of R.

(d) Simulate 500 samples of size 54 from a bivariate normal distribution with correlation coefficient equal to the correlation coefficient of the geyser data. For each sample of 54, calculate the correlation coefficient.

(e) Construct a histogram of the 500 observations of the correlation coefficient.

(f) Construct a q–q plot of the 500 observations of R from the bivariate normal distribution of part (d) versus the 500 observations in part (b). Do the two distributions of R appear to be about equal?

Step-by-Step Solution:
Step 1 of 3

Chapter 8: bivariate correlational research - When you see two things that are related, and you think are related, but actually have nothing to do with one another To be causal - Covariance - Internal validity - Temporal precedence Correlational strength - As you get a measurement change by this much on this chart or whatever - You get the same...
