Chapter 11 organizing test scores for statistical analysis

  1. 1. Organizing Test Scores For Statistical Analysis (part 2) Reference: Measuring and Evaluating Learning Outcomes in AL 1 and 2 Carlito D. Garcia Ed D
  2. 2. ORGANIZING SCORE THROUGH STEM-AND-LEAF PLOT
  3. 3. ORGANIZING SCORE THROUGH STEM-AND-LEAF PLOT • Stem-and-leaf plot – method of graphically sorting and arranging data to reveal its distribution.
  4. 4. ORGANIZING SCORE THROUGH STEM-AND-LEAF PLOT In this method of organizing scores, a numerical score is separated into two parts, usually, the first one or two digits and the other digits. The stem is the first leading digit of the score while the trailing digit is the leaf
  5. 5. The following procedure should be observed in organizing and presenting test scores in a stem – and-leaf plot:
  6. 6. 1. Split each numerical score or value into two sets of digit. The first leading set of digits is the stem, and the second or trailing set of digits is the leaf.
  7. 7. 2. List all possible stem digits from the lowest to highest.
  8. 8. 3. For each screw in the mass of data, write down the leaf number on the line labeled by the appropriate stem number
  9. 9. Let us illustrate how a stem-and-leaf plot is constructed with the us of the following periodical results in Biology. 30 74 80 57 32 40 55 59 31 77 82 59 90 51 54 62 33 46 65 49 92 69 66 41 42 50 68 48 57 71 68 59 60 53 49 63 53 44 81 68
