\n<\/strong>TOPIC: DATA AND INFORMATION
\n<\/strong>DEFINITION OF DATA
\n<\/strong>Data are raw, unorganized or unprocessed facts that need to be processed. Data can be something simple and seemingly random and useless until it is organised.<\/p>\n

\n<\/strong><\/p>\n

    \n
  1. \n
    Qualitative data i.e descriptive information\n<\/div>\n<\/li>\n
  2. \n
    Quantitative data i.e numeric information\n<\/div>\n<\/li>\n<\/ol>\n

    \n<\/strong><\/p>\n

      \n
    1. \n
      Continuous data: this can take any value. It is also known as measured data. It can take value within a range e.g 0-99, 10-20 etc.\n<\/div>\n<\/li>\n
