Manytimes real world data can be modeled by one of many different types of equations. By graphing a set of ordered pairs on a scatter plot, the relationship between the x and y values may be more obvious. The process of fitting data or points to an equation is known as There are many types of regressionsuch as linearquadratic, cubic, exponential, and not surprisingly sinusoidal. n this activity you will be creating a scatter plot of some actual data and then find the best sinusoidal equation that fits the data.
