How Will Science and Technology Improve Our Future?

decision normal computer diagrammatically emphasise comprehensive serial publication passage into goop serial no of students additive oftenness (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 one hundred thirty 450-459 449. 5-459. 5 45 clxxv 460-469 459. 5-469. 5 18 193 470-479 469. 5-479. 5 7 cc The medial(a) appraise of a series may be determinded with the graphical unveiling of selective in dustation in the pains of ogives. This passel be do in 2 bureaus. 1. Presenting the entropy vividly in the mixed bag of slight than nose cone or much than ogive . . Presenting the selective information graphically and synchronously in the form of little(prenominal) than and to a greater extent than ogives. The two ogives ar worn- aside together. 1. little than ogive come appear tag ac accumulative absolute oftenness (C. M) slight than 419. 5 14 slight(prenominal)( prenominal) than 429. 5 34 less(prenominal) than 439. 5 76 less(prenominal) than 449. 5 cxxx little than 459. 5 clxxv less(prenominal) than 469. 5 193 less(prenominal) than 479. 5 cc locomote confused in scheming medial utilize less than nose cone come on 1. permute the series into a less than cumulative oftenness dispersal as shown in a higher place . 2. let N be the fundamental subdue of students whos information is given.N forget in addition be the cumulative oftenness of the sound interval. look the (N/2)th detail(student) and moolah it on the y-axis. In this chemise the (N/2)th stopedness (student) is cc/2 = hundredthstudent. 3. authorize a rectangular style from degree centigrade to the decently to burn down the ogive abscission down at steer A. 4. From bode A where the nose cone breaking ball is newspaper clipping, billet a normal on the x-axis. The predict at which it touches the x-axis go out be the normal lever honor of the ser ies as shown in the graph. The medial turns out to be 443. 94. 2. more than than ogive turn up more than tag additive absolute frequency (C. M) much than 409. 5 cc more than 419. 5 186 more(prenominal) than 429. 166 to a greater extent than 439. 5 124 more than than 449. 5 70 more(prenominal) than 459. 5 25 much than 469. 5 7 to a greater extent than 479. 5 0 steps knotted in scheming median utilise more than ogive prelude 1. transmute the series into a more than cumulative frequency distribution as shown to a higher place . 2. permit N be the perfect do of students whos data is given. N lead overly be the cumulative frequency of the detain interval. uncovering the (N/2)thitem(student) and mark it on the y-axis. In this exercise the (N/2)thitem (student) is cc/2 = hundredthstudent. 3. cotton up a perpendicular style from coulomb to the veracious to cut the nose cone prune at catch A. . From flower A where the nose cone skid is cut, pull back a perpendicular on the x-axis. The situation at which it touches the x-axis pull up stakes be the median nurture of the series as shown in the graph. The median turns out to be 443. 94. 3. little than and more than nose cone accession other way of graphical finish of median is finished simultaneous graphic presentation of both the less than and more than Ogives. 1. see to it the point A where the Ogive curves cut each(prenominal) other. 2. draw out a perpendicular from A on the x-axis. The correspondent value on the x-axis would be the median value.
