Syllabus

Demonstration 1: A Memory Test Try to remember these word lists for a recall test Important: Try not to mix up the lists!! Why does that work? Demonstration 2: A Counting Test

Count how many times the ball is passed by the team in the white shirts (not the black shirts just the white) http://www.youtube.com/watch?v=Ahg6qcgoay4&watch_response

Why does that work? Demonstration 3: A Test of Disambiguation Right half of room Please close your eyes

Really ! . This is a rat

What is this a picture of? . This is a rat

This is a man What is this a picture of? . Everyday our biases affect how we see

the world and make decisions. Expectations affect our perceptions of the world. Our knowledge affects our perceptions of the world. New knowledge can

reshape what we see. Demonstration 4: Another Test of Disambiguation New knowledge can reshape what we see. .

Demonstration 1: Our prior knowledge will influence our memories inserting what was never there Demonstration 2: Our interests will influence what we see making invisible what is right in front of us Demonstration 3: Our recent experiences

will influence what we see making one interpretation much more likely Demonstration 4: Our current environment will influence what we see making images meaningful Not just tricks, but demonstrations that show even the

most basic interpretations of what we perceive and remember in the physical world is malleable and vulnerable. How we interpret social interactions and other problems are similarly vulnerable to bias. Careful measurement helps us account for these biases.

Why study stats? Every day we disambiguate what we see, remember, interpret and understand. Every time we see, or remember, or understand a problem we are vulnerable to biases.

Biases can impede or improve our decision making. (We want to minimize bad biases while maximizing good biases to our decision making) It is important to be aware of our own vulnerability to biases and illusions in social settings and in even the most basic daily

experiences. Statistics and research methods allow us to try to take into account our natural tendencies for specific kinds of biases When presented new information, we have no other

option than to relate it to what we already know there is no blank space in our minds within which new information can be stored so as not to contaminate it with existing information - Clifford Konold, Scientific Reasoning Research Institute, University of Massachusetts* * From Issues in Assessing Conceptual Understanding in Probability and Statistics

By Clifford Konold, University of Massachusetts. Journal of Statistics Education v.3, n.1 (1995) Why study stats? POWER!! Be able to defend that your methods are better

Why study statistics? Literacy in language of statistics

Study of stats provides opportunity for improving your computer literacy and management of databases and technical literacy

Improvement of own critical thinking (own life-long cognitive development) Introduction to Statistics in the Social Sciences

What is this course for? Improve skills for using data to inform our daily decisions and to avoid problems that arise from biases and illusions. Exploring the assumptions and principles underlying experimental methodologies and findings Practice critical evaluation of data and claims both in the popular media and in scientific publications

Practice completing calculations and applying the solutions to applied situations in daily life and in scientific inquiry Introduction to Statistics in the Social Sciences How will we do it? Lectures and reading

Grading Short writing assignments - 20 points (lowest 3 will be dropped) Homework assignments - 20 points (no assignments will be dropped) Laboratory activities - 60 points

Four multiple choice exams - 400 points Short Writing Assignments Regular short writing assignments most will be in-class some of these reflect in-class activities and interactions and it will not be possible to make them up worth a total of 20 points - writing form is available online

. Short Writing Assignment Form Homework Assignments Regular homework assignments will be assigned

in class. Some assignments will be from the textbooks, while others will be reports of other activities. Homework assignments will be worth a total of 20 points. Writing Assignments and Homeworks are meant to:

1)Provide opportunities to apply concepts in the class to other contexts to help generate semantically rich representations of the material 2) discuss applications of class concepts with others in the class 3) think critically and make distinctions between

related concepts 4) exploit our knowledge of elaborative encoding to maximize test performance. Exams Four exams - 100 points each

Multiple choice Make-ups only in cases of emergency All exams will be cumulative Exams are designed to: 1) encourage formation of factual

knowledge that can be called upon when integrating important concepts 2) encourage application of concepts to contextually rich situations 3) encourage critical thinking and highlight

distinctions between related concepts Evaluation and assignment of grades 1. Short writing assignments (20 points) 2. Homework (20 points) 3. Labs (60 points) 4. Exams (400 points)

Assignment of grades 500 possible points 450 - 500 = 400 - 449 = 350 - 399 = 300 - 349 =

Below 299 90% = A 80% = B 70% = C 60% = D =E

Introduction to Statistics in the Social Sciences Its better if you dont miss class !!! Cumulative course Start quickly

Attending class is a requirement Use notes and homework as a guide for what to study Math background and concerns . .

By the end of today... Requirements for the course What is descriptive vs inferential statistics? What is quantitative vs qualitative data? What is an independent vs dependent variable? How is a study that uses correlational methodology

different from one that uses experimental methodology? What are the four levels of measurement? Nominal Ordinal Interval Ratio

Missed Classes and exams If you do miss a class try to get notes from a classmate you are still responsible for information Make-up exams will be given only in cases of emergency If you know you will miss an exam, you may

make arrangements to take a similar exam at an earlier time. Thank you! See you next time!!
