for investigating the relationship between two quantitative‚ continuous variables‚ for example‚ age and blood pressure. Pearson’s correlation coefficient (r) is a measure of the strength of the association between the two variables. The nearer the scatter of points is to a straight line‚ the higher the strength of association between the variables. Also‚ it does not matter what measurement units are used (URL1) Spearman’s rank order correlation coefficient

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

Circadian Interference Establishment of a ‘normal’ circadian rhythm in sleep/wake cycle and core body temperature and the effects of a sleep deprivation event on that rhythm. Introduction: Circadian rhythms are well documented and researched all over the natural world. Humans are subject to a circadian rhythm as well; being naturally diurnal animals‚ humans sleep during the night and are active during the day. It is also known that circadian rhythms affect more than just sleep wake cycles‚ but
