Does a Person’s Income Relate to Their Age?

Variables  Annual Income Measured in Dollars per Year  Age of Individual Measured in Years

Data Collection Methods  Population of Taylorsville city = 59,102  Divided the population into 10 strata and gathered data from each. N= 5,910  We concluded that our desired sample size needed to be about 100 people. n= 100  We developed our random number range (k)by the following calculations: N/n = k 5,910/100 = 59 (rounded)  Then a random number was selected from the Random Number table (row 4 column 21) p=16 (p is a random number between 0-59)  Using the systematic method we gathered our data from the community, each gathering 20 pieces total and then compiled it all together to equal the 100 pieces of data.
