Arrange the following two sets of scores into 5 pairs of numbers (i.e. one \n" ); document.write( "each from sets A and B) that show a perfect negative linear relationship (i.e. r = -1) and do the calculation for r demonstrating this. \n" ); document.write( "Set A : 19, 11, 13, 25, 7 \n" ); document.write( "Set B : 48, 30, 42, 36, 44 \n" ); document.write( "---- \n" ); document.write( "The smallest \"A\" number would have to be paired with \n" ); document.write( "the largest \"B\" number: (7/48) \n" ); document.write( "-- \n" ); document.write( "Then next smallest with next to largest \n" ); document.write( "(11,44) \n" ); document.write( "etc. \n" ); document.write( "(13,42) \n" ); document.write( "(19,36) \n" ); document.write( "(25,30) \n" ); document.write( "---- \n" ); document.write( "Notice that the B numbers decrease 1 when the A numbers increase by 1. \n" ); document.write( "----- \n" ); document.write( "Now you can calculate \"r\": \n" ); document.write( "============================= \n" ); document.write( "r = [summation[(x-xbar)(y-ybar)]/[(n-1)sxsy] \n" ); document.write( "or \n" ); document.write( "r = [(sumx)(sumy)]/sqrt[(sumx^2)*sqrt[n(sumy^2)-(sumy)^2]] \n" ); document.write( "r = -1 (Got this using TI-84) \n" ); document.write( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
