The correct answer is: A. $0.6745\\left[ {\\frac{{1 – {r^2}}}{{\\sqrt n }}} \\right]$<\/strong><\/p>\n The probable error of correlation coefficient is a measure of how much the correlation coefficient is likely to vary from sample to sample. It is calculated using the following formula:<\/p>\n $$\\text{Probable error of correlation coefficient} = 0.6745\\left[ {\\frac{{1 – {r^2}}}{{\\sqrt n }}} \\right]$$<\/p>\n where $r$ is the correlation coefficient and $n$ is the number of pairs of observations.<\/p>\n Option A is the only option that includes the correct formula for the probable error of correlation coefficient. Option B is incorrect because it uses the wrong value for the constant $0.6745$. Option C is incorrect because it divides by $n$ instead of $\\sqrt{n}$. Option D is incorrect because it uses the wrong value for the constant $0.5758$.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”$$0.6745\\left[ {\\frac{{1 – {r^2}}}{{\\sqrt n }}} \\right]$$” option2=”$$0.5758\\left[ {\\frac{{1 – {r^2}}}{{\\sqrt n }}} \\right]$$” option3=”$$0.675\\left[ {\\frac{{1 – {r^2}}}{n}} \\right]$$” option4=”$$0.5758\\left[ {\\frac{{1 – {r^2}}}{n}} \\right]$$” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[701],"tags":[],"class_list":["post-33794","post","type-post","status-publish","format-standard","hentry","category-business-statistics-and-research-methods","no-featured-image-padding"],"yoast_head":"\n
