31, 27, 30, 28, 28, 29, 23

What can you say about the mean, median and mode of these values?

A) They are the same |

B) They are different |

C) Cannot say surely |

D) None of These |

Correct Answer:

A) They are the same |

Description for Correct answer:

Given data is 31, 27, 30, 28, 28, 29, 30, 31

I. Mode = 28

To find median the data can be written in ascending order.

23, 27,28, 28, 29, 30, 3.1.

II. Median = 28

III. Mean = \( \Large \frac{31+27+30+28+28+29+23}{7}=\frac{196}{7} \) = 28

For the given data, mean, median and mode are the same.
