1. RANKING OF SCORES Rolyn s. amolo teacher 1

2. RANKING: - IS THE RELATIVE PLACEMENT OR ARRANGEMENT OF MEASURES IN A SERIES ACCORDING TO MAGNITUDE, VALUE, OR QUALITY, FROM THE LOWEST TO THE HIGHEST OR VICE VERSA. - IT DOES NOT TAKE INTO ACCOUNT THE SIZE OF THE DIFFERENCE BETWEEN ANY TWO SUCCESSIVE MEASURES.

3. RANKING: - THE RANKS ARE SUCCESSIVE AND CONTINUOUS BUT THE DIFFERENCES VARY. - THEY ARE NOT EXACT MEASURES THEY SIGNIFY MORE OR LESS THE ACCOMPLISHMENTS OF PUPILS. HENCE, THE POSITIONS OF PUPILS INDICATED BY THEIR RANKS ARE RELATIVE, NOT ABSOLUTE.

4. RANKING: - FROM THE RANKS, IT IS POSSIBLE TO DETERMINE THE BRIGHT FROM THE DULL AND THE MEDIOCRE PUPILS. IT IS POSSIBLE TO DETERMINE PERCENTAGE OF PUPILS THAT SURPASS A PUPIL AND THAT SURPASSED BY HIM. RANKS ARE ALSO USED IN THE COMPUTATION OF THE COEFFICIENT OF CORRELATION.

5. PROCEDURE IN THE RANKING OF SCORES /MEASURES: 1. BY USING THE MASTER SHEET, ARRANGE THE SCORES FROM THE HIGHEST TO THE LOWEST, WRITING EACH SCORE AS MANY TIMES AS IT APPEARS.

6. PROCEDURE IN THE RANKING OF SCORES /MEASURES: 2. NUMBER THE SCORE CONSECUTIVELY, GIVING THE HIGHEST SCORE TENTATIVE RANK 1(ONE). NEXT HIGHEST 2, AND SO ON TO THE LOWEST SCORE. (The tentative rank of the lowest score is equal to the total number of case, “N”).

7. PROCEDURE IN THE RANKING OF SCORES /MEASURES: 3. ASSIGN THE RANKS AS THEIR REAL RANKS (RR). SCORES APPEARING MORE THAN ONCE HAVE THE AVERAGE OF THEIR ORDINAL NUMBERS (tentative ranks) AS THEIR REAL RANKS. (identical/similar scores have equal ranks).
