3. Interpretation
I am very interested in researching the association between family history and depression. So, variables are the family number who was ever depressed, including parents (S4BQ1 and S4BQ2), Bothers (S4BQ3C), Sisters (S4BQ4C), Sons (S4BQ5C) and Daughters (S4BQ6C). In addition, for this homework, I just interpret frequency tables from parents, sisters, and sons.
1, Yes; 2, No; 9, Unknown. Unknown is the missing data
Tables 1 shows the distributions of responses for blood/natural father ever depressed. 9.57 % of fathers (4126) is ever depressed and 74.70 % of fathers (32192) is never depressed. 15.72 % is unknown-- missing data.
Tables 2 shows the distributions of responses for blood/natural mother ever depressed. 16.55 % of mothers (7134) is ever depressed and 72.98 % of mothers (31448) is never depressed. 10.47 % is unknown- missing data.
Tables 3 shows the distributions of responses for any full bothers ever depressed. 9.06 % of brothers (3903) is ever depressed and 83.03 % of brothers (35778) is never depressed. 7.92 % of brothers is unknown (missing data).
Tables 4 shows the distributions of responses for any full sisters ever depressed. 11.02 % of sisters (4751) is ever depressed and 81.84 % of sisters (35266) is never depressed. 7.14 % of sisters is unknown (missing data).
