What is the dependent variable?
Would statistical test, ttest be sufficient?
Table 1. Baseline characteristics of participants from the MJ Health Screening Center, stratified by sex Men (n 41,879) Women (n 48,514) 51.4 11.0 Age, mean t SD years 51.7 t 12.0 Follow up duration, mean t SD years 8.3 1.2 8.1 1.4 BMI, mean SD kg/m2 24.2 3.2 24.2 11.8 Cholesterol, mean SD mg/dl 191.1 t 38.5 193.8 40.4 Triglycerides, mean t SD mg/dl 146.3 126.1 120.5 t 96.1 Glucose, mean t SD mg/dl 102.0 28.4 101.1 t 29.6Explanation / Answer
What is the independent variable?
For the given scenario, the independent variable is given as sex of the person.
What is the dependent variable?
The dependent variables for the given research study are given as age, follow-up duration, BMI, Cholesterol, Triglycerides, and glucose.
Would statistical test, t-test be sufficient?
For the given scenario, we need to use the two sample t test for the population means. The t-test will be sufficient in this case because we do not know the value for population standard deviation. We know that if we do not given the population standard deviation, we use the t test and if we are given a population standard deviation, then we use the z test instead of t test.
