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.
There are separate growth charts for weight, height, and head circumference. These simply represent the average weight, height, or head circumference of a bunch of normal children. You will see the percentile lines on the chart running parallel to each other. The percentile lines include 5%, 10%, 25%, 50%, 75%, 90%, and 95%. (For more information, see the CDC's web site: www.cdc.gov/growthcharts/). If a child's weight is at the 50th percentile line, that means that out of 100 normal children her age, 50 will be bigger than she is and 50 smaller. Similarly, if she is in the 75th percentile, that means that she is bigger than 75 children and smaller than only 25, compared with 100 children her age.
