(a)
To find:
The column percentages, strength and pattern of relationship.
Given:
The given statement is,
A researcher has conducted a survey on sexual attitudes for a sample of 317 teenagers The respondents were asked whether they considered premarital sex "always wrong” or “Not always wrong.” The following tables summarize the relationship between responses to this item and several other variables.
The given table of information is,
Premarital Sex  Gender  
Females  Males  Totals  
Always wrong  90  105  195 
Not always wrong  65  57  122 
Totals  155  162  317 
Approach:
If the maximum difference of the smallest and the largest column percentage in a row is less than 10%, it is said that there is a weak association between the categories.
If the maximum difference is between 10% and 30%, it is said that there is a moderate association between the categories and if the maximum difference is above 30%, then there is a high association between the categories.
Calculation:
From the given information,
The following table gives the column wise percentages based on gender.
Premarital Sex  Gender  
Females  Males  
Always wrong  58.06%  64.81% 
Not always wrong  41.94%  35.19% 
Totals  100%  100% 
The columns of the table are computed as,
Substitute the values from the given table of information,
(b)
To find:
The column percentages, strength and pattern of relationship.
