آمار پایان نامه ها و مقالات به زبان ساده

توضیحات

The idea of writing this book crossed my mind when I found that many students hate the statistics part of the articles and theses. Although statistics is not a sweet subject by nature, knowing it can help students read and write articles and theses more easily. This book is the result of my love for statistics and the result of reading a large number of books on the topic. I do not intend to confuse the readers with analyzing the data through software. I assume that someone else has done the statists part of the thesis or article and now the readers of this book are going to interpret the tables, graphs and the numbers which might seem frightening at the first glance. I welcome suggestions and criticism which will certainly be taken into account in future reprints of the book.

نمونه متن کتاب : 

In research and statistics, we usually deal with two terms: population and sample. Population means any group of individuals who are similar in some respects. Therefore, a group will be population when individuals have at least one common characteristic (e.g., the population of university students because they all study at the university).

There are many university students in Iran in different majors who are doing their undergraduate and postgraduate programs.  In fact, most of the time the population size is usually big and the people in a population have many characteristics and thus size and diversity are two problems related to population. To solve the problem of size, we get a sample from the population and to solve the problem of diversity, we limit the population to a specific group to which we wish to generalize our findings. The new narrowed down population is called target population.

Descriptive statistics simply is used to describe the sample. In the method section of an article, you should report the characteristics of the sample that you selected for the study. These characteristics include the number of people or cases in your sample, the number or percentage of males and females, the educational level, the mean score or average of the students, standard deviations, the number of the participants, and the minimum/maximum number that the participants got on the tests. This is called descriptive statistics.
