Information Is Based On Age And Gender

Better Essays

Information/Measurement My information is based on Age and Gender. Most of my mathematical data will use (years) as its units. However for standard deviation and the Chi-Squared test the expected values will be reduced to 3 significant figures. As for the P-values and the Critical values will be given in exact numbers. Mathematical Process As described in my introduction, I have found the mean, median, mode, and range of both genders. I got this data table from (http://www.infoplease.com/ipa/A0005061.html). This link leads to a table from the U.S Bureau of the Census. The table is displaying the median age at first marriage between the years of 1890-2010. The median of both genders were found in the 14th spot in the data table.The mode was observed in both genders. Also observed was that the most occurring ages for both male and female happened in the same 10 year time span. The process of finding the mean was shown below.
