What is Bootstrapping (In Statistics)? Bootstrapping is an interesting process or technique of assigning measure of accuracy. Depended upon calculation‚ Bootstrapping can be used to any statistic to measure estimation. Definition According to the Cambridge dictionary of statistics – “A confidence interval is a range of values‚ calculated from the sample observations that are believed‚ with a particular probability‚ to contain the true parameter value. A 95% confidence interval‚ for example‚ implies

CHAPTER 1 Individuals are the objects described by a set of data. Individuals may be people‚ but they may also be animals or things. A variable is any change of an individual. A variable can take different values for different individuals. A categorical variable places an individual into one of several groups or categories. A quantitative variable takes numerical values for which arithmetic operations such as adding and averaging make sense. The distribution of a variable tells us what values

root of the variance (Gravetter & Wallnau‚ 2013). It uses the mean of the distribution as a reference point and measures variability by considering the distance of each score from the mean. It is important to know the standard deviation for a given sample because it gives a measure of the standard‚ or average‚ range from the mean‚ and specifies if the scores are grouped closely around the mean or are widely scattered (Gravetter & Wallnau‚ 2013). The standard deviation provides researchers with information
