compound interest monthly/quarterly
Working out credit card interest over a number of days also requires this type of alteration to the formula.
Compound Interest example: $10,000 at 6% p.a. calculated monthly for 4 years.
r must become 0.06 / 12 and n must become 4 x 12 = 48
___________________________________________________________________
Credit Card Example: Interest charged at 19% p.a. calculated daily for 39 days.
r must become the daily interest rate (0.19 / 365) divided by 100 and n = 39

Calculating Interquartile range including outliers
In this topic, you'll be asked to make a 5 point summary and draw ad whisker and box plot.
In order to do this, you need to be able to do some calculations to work out:
1. The median (Q2)
2. Q3 - the upper quartile
3. Q1 - the lower quartile
4. The minimum (Q1)
5. The maximum (Q5)
6. Outliers
Outlier calculation involves finding the range within which the standard scores lie. When drawing a whisker and box plot you'll draw your maximum as the next lowest score if the highest score is an outlier, for example.
Q1 - (1.5 x IQR) = lowest standard score
Q3 - (1.5 x IQR) = highest standard score
Outliers lie outside these defined boundaries; and that is the very definition of why they're called 'Outliers'.
The Interquartile Range is used along with the calculation of the mean and standard deviation to standardise scores - like in the HSC.
