• 1. MEASURES OF POSITION FEATURING: DECILE FOR UNGROUPED AND GROUPED DATA Prepared by: ERIC M. DE GUZMAN MT-1
• 2. OBJECTIVES: ►Illustrate the Measure of Position: Quartile ►Calculate specified Measure of Position of a set of data.
• 3. MEASURES OF POSITION FEATURING: QUARTILE of GROUPED DATA Prepared by: ERIC M. DE GUZMAN MT-1
• 4. QUARTILE FOR GROUPED DATA ►The QUARTILE are the score points which divide a distribution into four(4) equal parts.
• 5. HOW TO SOLVE FOR A SPECIFIED QUARTILE OF GROUPED DATA?
• 7. HOW TO SOLVE FOR A SPECIFIED QUARTILE FOR GROUPED DATA? STEP 1 Gather Data. STEP 2 Prepare the table of frequency. CLASS INTERVAL FREQUENCY (f) LESS THAN CUMULATIVE FREQUENCY (<cf) LOWER BOUNDARY (LB)
• 8. HOW TO SOLVE FOR A SPECIFIED QUARTILE FOR GROUPED DATA? STEP 3 Use the formula for Percentile STEP 4 Interpret the result.
• 9. THE FORMULA FOR SPECIFIED QUARTILE(Qk) FOR GROUPED DATA LB -Lower Boundary k -{1, 2, 3} N <cfb fQk i - Population -less than cum. freq. below the assumed Qk -Freq. of the assumed Qk - Class interval NOTE: Assumed Quartile can be obtained by getting the value of

• 21. PERFORMANCE TASK SCORE DESCRIPTIONS 5 Performance is exceptionally executed, fully supported with concepts of Measures of Position 4 Performance is generally clear, some accounts are supported by concepts of Measures of Position 3 Performance is reflective of something learned. Lacks clarity and accounts have limited support. 2 Performance is unclear. 1 No performance. Conduct a survey about the annual salary of the parents of 50 Grade 10 Students Ernesto Rondon High School. Use different methods like estimation(ungrouped), interpolation(ungrouped) and quartile for grouped data, then compare. Be ready to present this to the class on Friday, March 1, 2019.
