Correlation coefficient is calculated with the formula below: (“Mark Gardener: Statistics For Ecologists Using R And Excel (Edition 2): Support: Exercises: Use Excel For Spearman Rank Correlation”)When r is equal to 1 or -1 it means that the two variables share a correlation and if r is equal to 0 it means little correlation or no correlation.To start solving the formula you find the mean of the sit x and the sit y by adding all the sits and dividing them with the number of sits. (X is average household income rates and Y is total firearms murder rates)Result Details & CalculationX Values? = 2532718Mean = 50654.36?(X – Mx)2 = SSx = 3410609437,52 Y Values? = 8475Mean = 169.5?(Y – My)2 = SSy = 2415360.5X and Y CombinedN = 50?(X – Mx)(Y – My) =1566796R Calculationr = ?((X – My)(Y – Mx)) / ?((SSx)(SSy))r = 1566796 / ?((3410609437.52)(2415360.5)) = 0.0173Meta Numerics (cross-check)r = 0.0173Firearms death rates in The United States 2015.STATE RATE DEATHSAL 19.6 958AK 23.4 177AZ 13.8 970AR 16.9 520CA 7.7 3,095CO 12.6 701CT 5.3 189DE 12.1 112FL 12 2,559GA 14.1 1,448HI 3.6 55ID 14.7 247IL 9.5 1,220IN 12.7 846IA 7.8 247KS 11.4 330KY 15.2 694LA 20.4 952ME 9.8 144MD 11.9 708MA 3 213MI 11.7 1,164MN 7.4 410MS 19.6 589MO 18.1 1,094MT 19.2 205NE 8.9 169NV 14.9 446NH 8.9 121NJ 5.4 475NM 18.6 390NY 4.2 849NC 12.5 1,289ND 12.8 92OH 11.9 1,397OK 18 706OR 11.4 486PA 11.4 1,485RI 4.7 51SC 17.3 850SD 11.1 96TN 16 1,075TX 11.7 3,203UT 12.8 367VT 9.6 70VA 10.9 946WA 9.8 718WV 14 278WI 10.4 613WY 19.6 113https://www.theguardian.com/news/datablog/2011/jan/10/gun-crime-us-statehttps://www.cdc.gov/nchs/pressroom/sosmap/firearm_mortality/firearms2015.csvhttps://www.census.gov/library/visualizations/2016/comm/cb16-158_median_hh_income_map.html
