Algebra.Com's Answer #13503 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! ARRANGE THE SCORES IN INCREASING ORDER...WE GET \n" ); document.write( "79,83,86,92,93 \n" ); document.write( "NOW \n" ); document.write( " MEAN =(79+83+86+92+93)/5=433/5=86.6 \n" ); document.write( "MEDIAN=MIDLE SCORE=86 \n" ); document.write( "MODE=SCORE WITH MAXIMUM FREQUENCY...HERE ALL HAVE SAME FREQUENCY ...ONE ONLY ...IN CASE 2 OR MORE SCORES HAVE SAME FREQUENCY WE TAKE THEIR AVERAGE AS THE MODE...HERE MODE COINCIDES WITH MEAN AS ALL SCORES ARE HAVING SAME FREQUENCY. \n" ); document.write( "MEAN IS CONSIDERED THE BEST REPRESENTATION FOR CENTRAL TENDENCY. \n" ); document.write( " |
