This document summarizes the key points from Lecture 1 of the N3318a Fall 2009 Elementary Statistics online course. It introduces the instructor, Abe Oudshoorn, and provides an overview of the course, including expectations, assignments, exams, and a research paper. It also discusses the importance of statistics for nursing and presents sample health data on nurses to illustrate statistical concepts. Key topics covered in the lecture include measurement scales, types of variables, and hypotheses.
Welcome to the series on Statistics for managers. In the beginner level, we'll cover basics of statistics, probability fundamentals and descriptive statistics.
We may have this question in mind that how the data is analysed, what are the ways in which we can summarize the data to make certain conclusions. In this lesson, we’ll go through a basic overview of the subject, Statistics. We’ll learn what is statistics, what do we mean by data and what are the types of statistical analysis which are done to understand the data. The video lesson is available on youtube-https://youtu.be/MupmSzG9NxI
These introductory statistics slides will give you a basic understanding of statistics, types of statistics, variable and its types, the levels of measurements, data collection techniques, and types of sampling.

Statistics is the science of dealing with numbers.
It is used for collection, summarization, presentation and analysis of data.
Statistics provides a way of organizing data to get information on a wider and more formal (objective) basis than relying on personal experience (subjective).

Poster Presentation
Students this project will allow you to formulate and hypothetically develop your own research project. The purpose of this project is for the student to follow all of the different steps in a research project on an already published article and presented as a poster presentation. A poster session or poster presentation is the presentation of research information by an individual or representatives of research teams at a congress or conference with an academic or professional focus. The work is usually peer reviewed. Poster sessions are particularly prominent at scientific conferences such as medical congresses.
Students will select a nursing research already published and following the article information you will create a poster presentation that include the below information:
The outline of the poster should include the following tabs (minimum requirements)
Abstract Outline:
-Title of Project

Assignment: Locating an Empirical Research Article
Empirical research articles document a study that is either quantitative, qualitative or a mixed methods research design. When authors write an empirical research article they typically follow a format that looks like this: Introduction/Background, Literature Review, Methodology, Findings, and Discussion. The authors recount literature on their specific research topic and describe in a systematic manner how the data was collected and then analyzed in order to answer the research question(s). Once the data is analyzed, they present the findings. Finally, they interpret the findings using past literature to help understand the findings.
What we broadly describe as a “quantitative study” includes numerical summaries that involve descriptive statistics (averages, standard deviations), correlations, and inferential statistics (such as T-tests, Chi Squares and other kinds of analyses). These kinds of studies can include certain elements such as per- and post-tests or survey results looking at correlations between variables.
Qualitative articles, on the other hand, use interviews, focus groups, observations, and written answers to questions. Rather than using statistics to summarize the study, these studies look at themes and present the material using words, phrases and often paragraphs to illustrate what they are representing.
To prepare for this assignment, review Week 1’s readings and resources on how to locate an empirical research article using the library’s databases.
For this Assignment,
· Locate an empirical research article that is either a quantitative or qualitative study from a peer reviewed social work journal for the final assignment.
· Do not select an empirical research article that describes a mixed methods study. The reason is because a mixed method study involves both a quantitative and qualitative component. You would have to do two reviews – one for the quantitative component and one for the qualitative component -- for the final assignment.
· Upload the article. Your instructor will review the article to make sure it is an empirical resear.

24. Some Background Terms Descriptive statistics: – for summarizing or describing a sample Inferential statistics: – for making inferences (conclusions) or to generalize from a sample to a population Sample: – part of population (what is used in most studies) Population: – all members of a particular group of interest
25.
26. Measurement Scales Nominal data : – distinct, unordered, qualitative e.g. gender, race ( Can you think of some others ?) Ordinal data : – ordered, distinct, qualitative categories e.g. health status, SES, others? Interval data : – ordered, quantitative categories, known intervals e.g. can be continuous (e.g. Celsius temp.) or discrete (e.g. parity), others? Ratio data : – most precise metric due to useful zero value e.g. BP, weight, height, Kelvin temp., others?

29. Types of Variables Independent : (exposure) – typically the variable(s) manipulated, controlled (or at least recorded) by the researcher e.g. dietary interventions, others? Dependent : (outcome) – typically the main variable of interest being measured by the researcher e.g. weight loss, others? Study conducted comparing effect of two dietary interventions on weight loss in obese children Scenario
30. Types of Hypotheses - 1 Null hypothesis (H 0 ): - proposes no difference or relationship between variables of interest ( basis for statistical inference ) e.g. There is no difference in weight loss between the two dietary intervention groups. Research hypothesis (H r ): - opposite of the null hypothesis (i.e. states that there is a relationship between variables) - also called alternative hypothesis or H a e.g. There is a difference in weight loss between the two dietary intervention groups Two sides of the same coin !
31. Types of Hypotheses - 2 Directional hypothesis : - proposes a specific direction for effect e.g. Intervention A will reduce weight more effectively than Intervention B Non-directional hypothesis : - no specific direction but an effect is predicted e.g. Intervention A and B will differ in their ability to induce weight loss
