sum of the data entries divided by the number entries. To find the mean of the sample data set the formula must be used: Sample mean x̄ = (∑x)/N = 446.1/30= 14.87 According to Larson and Farber, 2009, the median of a data set is the value that lie in the middle of the data when the data set is ordered. The given numbers in the table are in order, there are thirty entries (an even number). The median is the mean of the two middle entries. Median = (14.8+14.8)/2 = 14.8 According to Larson and Farber

of controversy, with prominent figures in science and philosophy arguing their views. Dating back to 200 AD, Sextus Empiricus was one of the first skeptics on induction and questioned whether induction is a valid form of scientific reasoning. Almost two thousands years later the debate still continues, however along the way many philosophers, most notably David Hume, have made major contribution to “the problem of induction debate”. Inductive reasoning has been commonly used for explanation, however

Comparing the Means of Two or More Groups When it comes to comparing the means of two or more groups, we must state that a null hypothesis. Random samples of each population must be chosen to be able to show the formula in a working status. To get a more accurate sample, a higher number of the populations should be used. There are two tees that can be used for testing depending on the sample size and if the standard deviation is known. The t-test, which test of whether a sample observation comes from
