\n<\/strong>STATISTICS: AVERAGE, MEAN, MEDIAN AND MODE
\n<\/strong>Average is a single value used to represent a set of numbers (i.e all value in as et data)
\nThe most common ly used statistics is average.
\nMEAN = SUM OF THE VALUE\/NUMBER OF VALUE
\n<\/strong>MEDIAN = THE NUMBER AT THE MIDDLE AFTER THE ARRANGEMENT OF THE DATA IN INCREASING OR DECREASING ORDER
\n<\/strong>MODE= THE VALUE THAT OCCURS MOST FREQUENTLY.
\n<\/strong>EXAMPLES:<\/strong> Calculate the mean, media and mode of the following data<\/p>\n

    \n
  1. 45, 50, 55, 54, 48, 53, 50, 55\n<\/li>\n
  2. 38, 35, 36, 30.8, 34.7, 37.9, 33.1\n<\/li>\n
  3. 3, 0,4,7, 0, 5, 3, 4, 0, 3, 6, 5, 5 ,4, 6, 5\n<\/li>\n<\/ol>\n

    Solution: MEAN= i.e the addition of all the given items, divided by the number of items<\/p>\n

    \u00a0Mean = 45+50+ 55+ 54+ 48+ 53+ 50+ 55
