X y = (x1) (y1) + (x2) (y2) N x (if n = 5) = n [ x1 + x2 + n3] 5 x = 5 [1 + 2 + 3] Data recorded in the sequence in which they are collected and before they are processed or ranked. Table 2. 1: ages of 50 students is quantitative raw data & ungrouped data & discrete because the ages are measured in years.
