Concepts 1. What is Inferential statistics? Inferential statistics uses observations of past occurrences or available data i.e. descriptive statistics to make decisions about future possibilities and/or the nature of the entire body of data. Inferential statistics draws conclusions or makes interpretations‚ predictions and inferences about a population based upon an analysis of a sample. 2. Give 2 different techniques which are used in descriptive statistics to represent the data. Tables or

to a four day school week‚ but not all of the benefits are for students. There are “Sixty-two school districts‚ constituting 34% of the 178 school districts in Colorado” and those sixty two school districts “schedule 7.5 hours per day for 144 days of school instead of the normal six hours for 180 days” (Dam). By switching to a four day school week‚ students grades and their attendance were improved. The school saved money and since there is only four days in the school week students and teachers
