Nowhere did we talk sample size and accuracy as of yet.\n\nI think we are slipping in advanced topics into basic courses.\n\n42% of students vs 5&% of teachers support uniforms.  \n\nThe answer that students are LESS LIKELY to support uniforms is true, HOWEVER, it is wrong because of sample size.  Where in the 3 videos did we invalidate the data because of sample size.  (Bivariate Data)  I have watched them multiple times and it is not discussed.\n\nhttps://www.khanacademy.org/preview/content/items/x1269f0895c03eb26\n\n    [[[{\"value\":\"42\"},{\"value\":\"58\"},{\"value\":\"57\"},{\"value\":\"43\"}],{\"values\":[false,true,false]}]]\n\nUser hash: 337377176\n\nMozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36\n\nMathJax is loaded, ready, queue length: 0\n\n\n\nstart of log\nloadModule mod /khan-exercises/utils/answer-types.js\nloadModule mod /khan-exercises/utils/tmpl.js\nloadModule mod /khan-exercises/utils/tex.js\nloadModule mod /khan-exercises/utils/jquery.adhesion.js\nloadModule mod /khan-exercises/utils/calculator.js\nloadModule mod /khan-exercises/third_party/MathJax/2.1/MathJax.js?config=KAthJax-9e2776ffe7d2006f16f36d0d55d9464b\nloadScript loading /khan-exercises/third_party/MathJax/2.1/MathJax.js?config=KAthJax-9e2776ffe7d2006f16f36d0d55d9464b\nloadScript loaded /khan-exercises/third_party/MathJax/2.1/MathJax.js?config=KAthJax-9e2776ffe7d2006f16f36d0d55d9464b\nstartTask...\nstartTask got task drawing-inferences-from-random-samples\nrenderExerciseTask drawing-inferences-from-random-samples\nstartTask...\nstartTask got task drawing-inferences-from-random-samples\nrenderExerciseTask drawing-inferences-from-random-samples\nstartTask...\nstartTask got task frequencies-of-bivariate-data\nrenderExerciseTask frequencies-of-bivariate-data"}}
