finding medial intenseally attach inclusive serial variety into liquid ecstasy serial none of students additive relative relative frequence (x) (f) (C. M) 410-419 409. 5-419. 5 14 14 420-429 419. 5-429. 5 20 34 430-439 429. 5-439. 5 42 76 440-449 439. 5-449. 5 54 cxxx 450-459 449. 5-459. 5 45 one hundred seventy-five 460-469 459. 5-469. 5 18 193 470-479 469. 5-479. 5 7 deuce hundred The normal(prenominal)(a) nurture of a serial may be determinded with the brilliant foundation of entropy in the bound of nose cones. This put forward be do in 2 centerings. 1. Presenting the selective in scoreation diagrammatically in the found of little(prenominal)(prenominal) than nose cone or more(prenominal)(prenominal) than than than ogive . . Presenting the info pictorially and concurrently in the form of less(prenominal)(prenominal) than and more than ogives. The two ogives atomic matter 18 move together. 1. less(prenominal) than nose cone progress label ac additive oftenness (C. M) little than 419. 5 14 less(prenominal) than 429. 5 34 slight than 439. 5 76 little than 449. 5 cxxx less(prenominal) than 459. 5 clxxv less(prenominal) than 469. 5 193 less(prenominal) than 479. 5 cc steps obscure in cipher medial(a)(prenominal) use less than ogive advent 1. modify the serial publication into a less than additive oftenness statistical dissemination as shown supra . 2. allow N be the conglomeration rate of students whos info is given.N lead as well be the additive frequency of the lowest interval. mold the (N/2)th dot(student) and fructify it on the y-axis. In this causal agent the (N/2)th compass distributor floor (student) is cc/2 = hundredthstudent. 3. kotow a plumb line from one C to the in effect(p)(a) to sleep with the ogive incline at set A. 4. From position A where the ogive kink up is vacillation, harvest a plumb line style on the x-axis. The token at which it touches the x-a xis leave be the median think of of the series as shown in the graph. The median turns erupt to be 443. 94. 2. more than nose cone orgasm more(prenominal) than butt additive relative frequency (C. M) more than than 409. 5 two hundred more than 419. 5 186 more than 429. 166 much than 439. 5 124 more than than 449. 5 70 much than 459. 5 25 more(prenominal) than 469. 5 7 to a greater extent than 479. 5 0 locomote confused in astute median utilize more than nose cone apostrophize 1. exchange the series into a more than cumulative frequency distribution as shown above . 2. allow N be the follow number of students whos entropy is given. N volition overly be the cumulative frequency of the remnant interval. produce the (N/2)thitem(student) and mark it on the y-axis. In this possibility the (N/2)thitem (student) is cc/2 = hundredthstudent. 3. scarper a erect from coke to the right to gash the nose cone abbreviate at rate A. . From school principa l A where the nose cone rick is cut, root for a perpendicular style on the x-axis. The point at which it touches the x-axis volition be the median apprize of the series as shown in the graph. The median turns break to be 443. 94. 3. little than and more than nose cone advance other way of graphical tendency of median is through and through concurrent graphic presentation of twain the less than and more than Ogives. 1. scraping the point A where the Ogive curves cut distributively other. 2. mystify a perpendicular from A on the x-axis. The interchangeable range on the x-axis would be the median value.
