These values represent different force readings collected over a specific period. The data is arranged in a matrix format for easy comparison and analysis. Each number in the set corresponds to a specific measurement unit relevant to the context of the study.

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
