A Loud Noise
In a scale measuring noise, an increase in 10 dB is a 10 time increase in power. Mathematicians examine the data graph of a real world exponential growth, with no logarithmic scale, and then create two equations relating the decibels and...
Balanced Assessment
Stock Market
Analyze trends in the stock market using histograms. Future economists use data presented in a histogram to find periods of greatest increase and decrease. They also draw conclusions about days that would be best to invest.
