Questions

The following table gives production yield per hectare of wheat of 100 farms of a village.

Production Yield | 50-55 | 55-60 | 60-65 | 65-70 | 70-75 | 75-80 |

Number of Farms | 2 | 8 | 12 | 24 | 38 | 16 |

Change the distribution to a more than type distribution and draw its ogive.

detailed solution

Correct option is A

Converting the given distribution to a more than type distribution, we get

Production Yield (kg/ha) | Number of farms |

More than or equal to 50 | 100 |

More than or equal to 55 | 100-2 = 98 |

More than or equal to 60 | 98-8= 90 |

More than or equal to 65 | 90-12=78 |

More than or equal to 70 | 78-24=54 |

More than or equal to 75 | 54-38 =16 |

From the table obtained draw the ogive by plotting the corresponding points where the upper limits in x-axis and the frequencies obtained in the y-axis are (50, 100), (55, 98), (60, 90), (65, 78), (70, 54) and (75, 16) on

this graph paper. The graph obtained is known as more than type ogive curve.
