Unfortunately, he couldn’t repeat the success in another tournament conducted on a Thursday but won many other tournaments conducted on different days. Kevin was thrilled and concluded that every Thursday was supposed to be his lucky day. When he started playing professional games, he had his first win on a Thursday, and on all other days, he failed. Kevin is a poker player and is addicted to the game.But this can be a case of regression to the mean because even if no treatment is given, the blood pressure or sugar can fall due to various other reasons like measurement error or biological variation and can be for a short duration. This result can make us believe that the treatment is effective. They are measured again after providing treatment and found that the mean value of the extreme group (people with high blood pressure or sugar) changes and is closer to the mean of the whole population. Consider values measured from people with high blood pressure or blood sugar.It is not uncommon when measurement closer to the mean follows extreme large or small measurements. Hence, Its occurrence has a negative impact when natural variation in repeated data is perceived as a real change. This phenomenon supports certain outcomes based on chance, not statistical analysis Statistical Analysis Statistical analysis refers to the analysis of data collected to derive patterns, trends, or other meaningful conclusions. If the sample selected from the population is nonrandom, also the first measurement is an extreme value, and the next measurement taken is imperfectly correlated or has a weaker correlation, the RTM effect will be more obvious and strong. Compared to the mean observed for the first group, the second group or observation set mean will be closer to the population’s mean Population's Mean The population mean is the mean or average of all values in the given population and is calculated by the sum of all values in population denoted by the summation of X divided by the number of values in population which is denoted by N. Regression to the mean points to an extreme or unexpected outcome reverted to an average value if tested for the second time.
