Answer the following activities.

Set B: The following frequency distribution table shows the scores of 40 students in their 107-item Final Examination in Guidance and Counseling. Class Class Frequency Class Deviation Interval Boundaries (0 Frequency Mark (mp) fmp (d) Measures of Centrali Problem Set Points S stem LONG EXAM #1 Activit 8 Points System 3 point for each correct column (0 point for a single mistake in the column) Deviation Mean 10 points for each correct Median measures of centrality with correct computation Provisions for Mean, Median, and Mode Indicators 1 point for each correct measures of centrality without/wrong computation; 0.5 point for each measure of centrality with computation but wrong answer; and 0 oint for no answer and no com utation. Page 10 of11 Example of crude median: 45, 43, 40, 37, 33, 31, 28, the median is 37; the middle number. How if the set of scores is even, for example, 45, 43, 40, 37, 35, 33, 31, 28? Get the two middle numbers, add then divide it by 2; 37 plus 35 equals 72, 72 divided by 2 equals 36. For the refined median, use the formula: Man = LL + ( 2 - cf ) : Where: Man = the median LL = or EL, the exact lower limit N = the number of cases or scores (or population) cf = or cfb, the cumulative frequency equal to or next lower than N/2 = or fm, the frequency of the median class = the interval Example: From the frequency distribution table, we need to look at the location of the 0 deviation, from the class interval to the cumulative frequency.
