Essentials of Statistics for Nursing - Assignment Example

Demographic factors such as age, gender, level of education, and area of residence are other possible variables for the study. Mean, range and standard deviation will be calculated for both self-efficacy score, age, and educational sessions because the variables are measured on a ratio scale that allows for the calculation of descriptive statistics (Heavey, 2011).

Data points for using frequencies and percentages

Frequency and percentage will be used for gender, level of education, and area of residence because the variables are measured on an ordinal scale of the variables. The lack of equal interval on the magnitude and absolute zero properties does not allow to use of mean, range, and standard deviation in describing the variables (Heavey, 2011).  

A possible method for analysis of collected data

The task force could use a t-test to investigate the relationship between self-efficacy score and the number of educational sessions. The statistic would test a hypothesis for the significance of a relationship between the two variables (Heavey, 2011).
