Why study stats? Let’s start with four short demonstrations
Memory test Try to remember these word lists for a recall test Important not to mix up the lists!!
Important to be aware of our ownvulnerability to biases and illusions in social settings and in basic experiences Combat biases in our own thinking Please help me with a demo
Please close your eyes Right half of room
. This is a rat
Please close your eyes Left half of room
. This is a man
Please open your eyes Everyone
. What is this a picture of?

. Expectations affect our perceptions of the world. Everyday our “biases” affect how we see the world and make decisions. Our knowledge affects our perceptions of the world.
. By manipulating our knowledge we can influence our perceptions of the world.
. Expectations affect our perceptions of the world. Everyday our “biases” affect how we see the world and make decisions. Our knowledge affects our perceptions of the world. Not just “perceptions” but memory and how we experience the physical and social worlds around us. http://www.youtube.com/watch?v=oSQJP40PcGI http://www.youtube.com/watch?v=JX2BJC12uXQ&feature=related http://www.youtube.com/watch?v=Ahg6qcgoay4&watch_response
Everyday our “biases” affect how we see the world and make decisions. 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=JX2BJC12uXQ&feature=related http://www.youtube.com/watch?v=Ahg6qcgoay4&watch_response http://www.youtube.com/watch?v=oSQJP40PcGI
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 the characteristics of physical events or objects are similarly vulnerable to bias. Careful measurement helps us account for these biases.
Every day we disambiguate what we see, remember, interpret and understand. Why study stats? 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 than others – lead to advancement
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 • Data management • Too much??! - Stats can help you simplify • Too little ??!? – Stats can help you fill in the blanks (smartly) • Career Advancement (how helpful you are to others) • 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 • Laboratory research and projects • In-class assignments • Homework assignments
Introduction to Statistics in the Social Sciences Grading • Short writing assignments - 20 points (10 of them - lowest 3 will be dropped) • Homework assignments - 20 points (lowest grade will be dropped) • Laboratory activities - 60 points • Four multiple choice exams - 400 points
