Answer 1

${\large{\pmb{\sf{\underline{\maltese \: \: Correct \; Question...}}}}}$

The following are the weight in kg of 20 students of a class:

25, 16, 17, 15, 23, 10, 09, 65, 6, 17, 15, 16, 23, 25, 16, 15, 23, 09 10, 06

What is the range of the data?

${\large{\pmb{\sf{\underline{\maltese \: \: Knowledge \; Required...}}}}}$

${\quad \quad \quad{\pmb{\sf{\circ \: \: About \: Range...}}}}$

To find range we have to subtract the highest term with the lowest term of the given observation.

${\large{\pmb{\sf{\underline{\maltese \: \: Solution...}}}}}$

The range of the data : 25, 16, 17, 15, 23, 10, 09, 65, 6, 17, 15, 16, 23, 25, 16, 15, 23, 09 10, 06 is 59.

${\large{\pmb{\sf{\underline{\maltese \: \: Full \; Solution...}}}}}$

⟹ Highest term is 65

⟹ Lowest term is 6

⟹ Range = Highest term - Lowest term

⟹ Range = 65 - 6

⟹ Range = 59

${\large{\pmb{\sf{\underline{\maltese \: \: About \; mode...}}}}}$

To find mode we have to check that which number came more time. And according to the question there are no mode because all numbers are just coming for a time.

${\large{\pmb{\sf{\underline{\maltese \: \: About \; median...}}}}}$

To find median firstly we have to make the terms in ascending or descending order as we want. Then we have to check the middle term there. Then we get our answer means middle terms in that sequence is the median but if there is no middle term coming means for example there are total 6 terms then it obvious that in middle no term will come because it be even then we have to add two middle terms then we have to divide it by two. Ascending order? Small number to big number. And we get our final result!

${\large{\pmb{\sf{\underline{\maltese \: \: About \; mean...}}}}}$

To find the mean of any term we have to add all the given digits firstly then when the sum came then we have to divide it by the total number of already given terms. And then at last we get our final result as mean. Formula to find mean is given below:

${\small{\underline{\boxed{\sf{\rightarrow \dfrac{Sum \: of \: terms \: or \: observations}{Total \: number \: of \: terms \: or \: observations}}}}}}$
