Students then could be asked what effect this alteration had on such basic descriptive statistics as the mean and median of this data set and to explain why these. A good exploratory exercise could be developed, if the data set was altered by replacing the largest height of 74 inches by 84 inches, as indicated in Figure 1. The DESCRIBE feature of Minitab provides the basic descriptive statistics for this data set such as the mean, the median, and the standard deviation. The Minitab data used in Figure 1 is a random sample of the heights in inches of thirty Statistics I students at Le Moyne College. Instead, students should be asked to look for patterns in graphs and to observe any relationships between data sets and the summary statistics which describe these sets.

To direct students to use Minitab merely to find graphs, measures of central tendencies, measures of dispersions and measures of location reduces descriptive statistics to a series of mechanical exercises.

Consider Minitab exercises that deal with descriptive statistics. They deal with the 'what if possibilities'. These types of questions are many times overlooked in introductory statistical courses. Why is a particular statistical procedures used ? What results should be expected ? What do the results mean in the context of the real world setting of this problem ? Second, explorative questions should be raised. First, good interpretive questions should be raised. Two major types of questions should be examined when statistical analysis is conducted by using Minitab. By the end of the 1970s, it had become the leading instructional tool for basic. The essence to strengthening students' critical thinking skills is learning to ask students the proper questions. Following its inception at PSU, MINITAB rapidly grew in popularity. The results show that females have the higher mean.This paper will explore how, in an introductory college statistical course, these skills can be enhanced in the Minitab environment. For question 2, This can be found by going to Stat > Basic Statistics > Display Descriptive Statistics and selecting GPA for the variables box and Gender for the By Variable box. There were 9 students who did not answer this question - N*. Which Gender reported having the higher mean GPA (column C2)?ДЄ) Answered = 241 Higher Mean GPA = Female Д«) Answered = 250 Higher Mean GPA = Female Д¬) Answered = 241 Higher Mean GPA = Male Д) Answered = 250 Higher Mean GPA = Male ДЇeedback: Number who answered is 241. It aims to help patrons familiarize with five of the most popular statistical software. How many students answered the question regarding SAT Math scores (Column C14)? 2. This guides serves as an introduction to some Statistical Analysis Software.
