Make 2 sets of data 8 numbers each between 1 and 25. Then calculate the median and IQR for each data set.

vlada-n [284]

The median of the data set will be 15.5. The data set is in between the 1 to 25.

<h3>What is median?</h3>

Median is such a number for the arranged data set in ascending or descending order, such that to its left and to its right belong the same number of observations.

The data set between the number is;

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25

The value of IQR for data set is;

First Quartile Q1 = 6.5

Second Quartile Q2 = 13

Third Quartile Q3 =19.5

The median of the data set is;

$\rm Median= \frac{15+16}{2} \\\\ Median= 15.5$

Hence, the median of the data set will be 15.5.

the results of a poll indicate that between 33% and 37% of the population of a town visit the library at least once a year. what

The margin of error is ±2%

<h3>What is Margin error?</h3>

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.

Let x be margin of error and y be the percentages of the population.

So,

y-x =33%

y +x = 37%

Solving above equations

2y= 70

y= 35%

and x= 2%

Hence, the margin of error is ±2%.
