Department of Nursing Scholars Code. Good Luck! Question 25 Squaring the Pearson correlation coefficient (r2) tells us that O how much variance is shared by the two variables. O the direction of the association (positive or negative). O whether or not we need to conduct a Spearman test of correlation instead. O whether the correlation is statistically significant at the 0.05 level. * Previous ASUS VivoBook ,囝 f6 f80/ home f9 % 3 4 5 6 & 7 8 %24
The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ?(Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ? yet. However, there is a quick way to determine if the sample evidence based on ? is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of r to determine if ? ≠ 0. We do this by comparing the value |r| to an entry in the correlation table. The value of ? in the table gives us the probability of concluding that ? ≠ 0 when, in fact, ? = 0 and there is no population correlation. We have two choices for ?: ? = 0.05 or ? = 0.01. (a) Look at the data below regarding the variables x = age of a Shetland pony and y = weight of that pony. Is the value of |r| large enough to conclude that weight and age of Shetland ponies are correlated? Use ? = 0.05. (Round your answer for r to four decimal…
