One way, to describe the relationship between real interest rates and inflation, is based on our experience with the monetary theory of the price level. The quantity theory of money can be used under certain assumptions as a good description of the long-run relationship between money and prices.ne way, to describe the relationship between real interest rates and inflation, is based on our experience with the monetary theory of the price level.

What Are Percentiles? Percentiles are measurements that show where a child is compared with others. On the growth charts, the percentiles are shown as lines drawn in curved patterns. When doctors plot a child's weight and height on the chart, they see which percentile line those measurements land on.
Percentile: the value below which a percentage of data falls. 80% of people are shorter than you: That means you are at the 80th percentile. If your height is 1.85m then 1.85m is the 80th percentile height in that group. The data needs to be in order! To calculate percentiles of height the data needs to be in height order (sorted by height). To calculate percentiles of age the data needs to be in age order. And so on. A related idea is Deciles (sounds like decimal and percentile together), which splits the data into 10% groups: The 1st decile is the 10th percentile (the value that divides the data so that 10% is below it)
