Suppose you're given a set of data. Arrange it in ascending order, from smallest to largest.

The "range" of this data can be thought of as "smallest to largest." Alternatively, you could subtract the smallest value from the largest and call that the "range" of the data set. That's it.

On the other hand, finding the IQR of a data set requires more work. Again, arrange the data in ascending order. Now identify the median as well as the first and third quartiles. Subtract the first quartile from the third quartile. The result is your IQR.

The tradeoff in doing more work to find the IQR is that the results tell us more about how the data set is distributed.

It is defined as the difference between the largest and smallest values in the middle 50% of a set of data. To compute an interquartile range using this definition, first remove observations from the lower quartile. Then, remove observations from the upper quartile.

If you pull eight coins from your pocket, and none of them are pennies, what is the most money that you could have? The least?

If you're based in the UK, you could say up to £800 as we have £100 coins here.

Lowest amount? Besides our penny our least valuable coin is the 2 penny coin. So barring pennies the least you could pull out of your pocket if you're based in the UK is 16p.

How much money will she have if she doesn't buy any packs of baseball cards? $16 $18 $19 $20

GrogVix [38]

The amount of money that Carly would have left if she doesn't buy any packs of baseball cards is $20.

<h3>How to calculate the amount of money?</h3>

In order to calculate the amount of money that Carly would have left if she doesn't buy any packs of baseball cards, we would determine the cost of each baseball card as follows:

Let the cost of each baseball card be x.

Let the number of cards bought be n.

Translating the word problem into an algebraic expression, we have;

x - n = 16

x - 2n = 12

Solving the simultaneous equations by elimination, we have:

n = 4

Therefore, Carly's minimum balance is given by:

x - n = 16

x = 16 + n

x = 16 + 4

x = $20.
