Answer:

Interquartile Range

The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.

Interquartile Range = U pper Quartile − Lower Quartile

Problem

Find the interquartile range of eruption duration in the data set faithful.

Solution

We apply the IQR function to compute the interquartile range of eruptions.

> duration = faithful$eruptions     # the eruption durations

> IQR(duration)                     # apply the IQR function

[1] 2.2915

Answer

The interquartile range of eruption duration is 2.2915 minutes.

Exercise

Find the interquartile range of eruption waiting periods in faithful.

What is 12 divided by 3/4?
kap26 [50]
12 ÷ 3/4:

First, there are many ways to divide a whole number by a fraction. In my way, I take acknowledgment to the rules. There are other ways to do this, like the reciprocal way. To first get started, I'm going to give you the rule which is: (a ÷ b/c = a × c/b). We can now replace our numbers in the variables place.
12 \times  \frac{4}{3}

Second, we can simplify. To do so, (12 × 4 = 48). 48 is our new numerator while we keep the denominator we started out with (3). 
\frac{48}{3}

Third, this is where long division comes in handy. I can't exactly do it on a website, but I am going to try. It is best if done on a piece of paper.

\Mydiv3{%&#10;$\strut#$\kern.25em\smash{\raise.3ex\hbox{$\big)$}}$\mkern-8mu&#10;        \overline{\enspace\strut#48}$} \\ \sf Multiply \ 4 \div \ 3 =1 \ (remainder \ 1) \\ \sf Bring \ down \ 8 \\ \sf 18 \div 3 = 6 \\ \sf 48 \div 3 = 16
