Finding Typical Graphically

Marks

inclusive series| Conversion in to

exclusive series| No . of students| Cumulative Frequency

(x)| | (f)| (C. M)

410-419| 409. 5-419. 5| 14| 16

420-429| 419. 5-429. 5| 20| thirty four

430-439| 429. 5-439. 5| 42| seventy six

440-449| 439. 5-449. 5| 54| 140

450-459| 449. 5-459. 5| 45| 175

460-469| 459. 5-469. 5| 18| 193

470-479| 469. 5-479. 5| 7| 200

The typical value of the series may be determinded through the graphic demonstration of data in the form of Ogives. This could be done in two ways. 1 ) Presenting the info graphically in the form of 'less than' ogive or 'more than' ogive. installment payments on your Presenting the information graphically and simultaneously by means of 'less than' and 'more than' ogives. The two ogives are sketched together. 1 ) Less than Ogive approach

Marks| Cumulative Consistency (C. M)

Less than 419. 5| 16

Less than 429. 5| thirty four

Less than 439. 5| seventy six

Less than 449. 5| 135

Less than 459. 5| a hundred seventy five

Less than 469. 5| 193

Less than 479. 5| 2 hundred

Steps involved with calculating typical using lower than Ogive procedure - 1 . Convert the series into a 'less than ' total frequency division as proven above. installment payments on your Let N be the entire number of college students who's data is given. N will also be the cumulative consistency of the previous interval. Find the (N/2)th item(student) and mark it around the y-axis. In such a case the (N/2)th item (student) is definitely 200/2 sama dengan 100th student. three or more. Draw a perpendicular from 100 towards the right to slice the Ogive curve for point A. 4. Via point A where the Ogive curve is definitely cut, draw a verticle with respect on the x-axis. The point at which it touches the x-axis is definitely the median benefit of the series as shown in the chart.

The median turns out to be 443. 94.

2 . More than Ogive approach

A lot more than marks| Cumulative Frequency (C. M)

More than 409. 5| 200

Much more than 419. 5| 186

More than 429. 5| 166

More than 439. 5| 124

Much more than 449. 5| 70

A lot more than 459. 5| 25

More than 469. 5| 7|...
