For Thurs, Dec 19

Here's what to aim to complete in OLI by Thurs:

Screens 104-106
Unit 3, Mod 6: Finding Probability of Events

Investigate Difference between Disjoint and Independent Events

In case you want to work ahead, the plan is to finish Module 6 by Jan 9.

In class on Thursday, we will be collecting survey data, based on your plans:

• Ethan, Ben, Cammy and I will be going to the shopping center to collect data
• Margaret and Bobby will be finishing up their data collection
• Baird and Ashlin will be collecting data from PLCers

The next step will be to analyze your data, so if you have time, you can work on plans to enter the data into a dataset.

For Thus, Dec 12

Hope you all have a chance to enjoy today's snow. Here's what to aim to complete in OLI by Thurs:

Screens 100-103
Unit 3, Mod 6: Finding Probability of Events

Alison

For Oct 24

Here's the next bit to get done for this week.

Screens 48-55
Unit 1, Mod 2: Examining Relationships

Linear Relationships

--Calculate Correlation Coefficient

--Calculate & Plot a Linear Regression Line

In class on Thursday we will begin with a discussion of statistics in the big outside world. You know the drill.....

Following that you will work on analyzing and graphing the m&m data in response to one of the questions we identified last week. Feel free to add any additional questions to our planning document.

Alison

For Oct 17

Hopefully you all are moving ahead with the OLI work. Here's what you should try to get done for this Thursday:

Screens 34-47
Unit 1, Mod 2: Examining Relationships

Role-Type Classification

Case I One Categorical & One Quantitative Variable

Case II Two Categorical Variables - Calculate Two-Way Table

Case III Two Quantitative Variables: Scatterplots - Create a Scatterplot

In class on Thursday we will begin with a discussion of statistics in the big outside world. Bring to class any uses of statistics which you come across in your daily life, so we can discuss how the statistic(s) is being used.

Following that we will discuss graphs, both problematic ones and good ones. Be on the lookout for a graph which you would like us to discuss and bring the graph to class. We will also be planning the next steps with the m&m data.

Alison

In class on Thursday, we will begin with a discussion of statistics in the big wide world. Bring to class any uses of statistics which you come across in your daily life, so we can discuss how the statistic(s) is being used. To follow, we will work on finishing the M&M data collection.

Alison

For next week, Sep 26

Each week I will post to the blog, providing a list of OLI content to try to complete that week. The idea is to give you a goal so you can make progress. If you'd like to work ahead, feel free to do so.

GOAL--Try to get through screen 12 by Thursday Sep 26:

• Introduction, Learning Strategies, and Big Picture -- screen 1 thru 5
• Unit 1: Exploratory Data Analysis: Introduction -- screen 6 thru 7
• Mod 1: Examining Distributions -- screen 8 thru 9
• One Categorical Variable - Create a Table & Pie Chart -- screen 10 thru 12

Remember to keep your eye out in your daily life for interesting applications of statistics. Bring these uses to class so we can discuss how the statistic(s) is being used.

Let me know if you are having any issues.

Getting started with the OLI Probability and Statistics course

Good class today. I'm looking forward to our work together this year :)

The following guidelines will help you get set up with the OLI Probability and Statistics course and get your "statistical software" figured out. Let me know if you have trouble with any of these steps:

• OLI Probability and Statistics course: As I mentioned today, there is both a free version that you can use independently, or you can pay $25 to be in my OLI "class". The only advantage of being in my class is that I can see your work and may notice when you need help. 
• Free version: Go to the OLI Probability and Statistics page, click "Enter Course", and then click "Sign up" to make an account. You will then be on the "My Courses" page and you can get started with the course.
• Paid version: To register to be a student in my OLI "class", go to the Open Learning Initiatives website, enter the admit code "snieck-12" and follow the instructions to register for the course. You will need to use the online payment system to pay the $25 fee. (There is a note that the method of registering will be changing; let me know if you have any trouble.)
• Statistical Software: Exercises in the online course are designed for use with a number of different software packages. I suggest any of the following:
• R, a free software environment for statistical computing and graphics (If you need help, I suggest asking Margaret or Ben as they both have experience with getting this set up.)
• Microsoft Excel, spreadsheet software which comes installed on many pc computers (I recommend this option if you have Excel and would like to become more proficient with spreadsheets.)
• LibreOffice Calc (or OpenOffice Calc), free open source spreadsheet software (I can provide instructions for the exercises using Calc if anyone decides to use this; the instructions are not directly available in the OLI Statistics course.)
• If you are choosing to use spreadsheet software to do the statistics work I suggest spending some time learning about spreadsheets, as a first step, in particular working with cells, formulas and functions, and creating charts:
• Basic Excel tutorial - covers the basics, except pivot table (which won't be needed right away).
• Calc Guide Working with Spreadsheets - chapters 1-3, 7 and 8

Let me know if you have any questions.
