The big bang theory is a scientific origin story‚ based on real evidence which explores history in thresholds from the big bang to present.

There are 18 data sets that accompany the text book. These data sets can be found when you enter StatCrunch from the course. Here is a list of the data sets and the variables found in those data sets. If there is no listing of variables then they are easily identified in the data set. Data Set 1: Health Exam Results (both male and female) AGE is in years‚ HT is height (inches)‚ WT is weight (pounds)‚ WAIST is circumference (cm)‚ PULSE is pulse rate (beats per minute)‚ SYS is systolic blood pressure
