Introduction to Probability

In class students were introduced to probability and talked about how we can use information about the long run to make predictions about what will happen in the short run.

The notes are attached below and there is no homework.

Notes - Introduction to Probability

Quiz - Collecting Data

In class students took a quiz on collecting data.  Afterwards, they were given a group project to complete with various deadlines. 

The homework is listed below and the project is attached.

Group Project - Collecting Data

HW - Read Chapter 14 - From Randomness to Probability

Review - Collecting Data

In class students reviewed the various ways in which we collected data which are as follows: simulation, sample survey and experiment. 

The notes on the section are attached below as is the homework.


Notes - Review - Collecting Data



Practice Quiz - Collecting Data

Answer Key - Practice Quiz - Collecting Data

HW - Study for Quiz
          Investigative Task - Forklifts and Backhoes
          Read Chapter 14 - pgs. 324-336 - "From Randomness to Probability"

Experimental Design (2)

In class we continued to talk about experimental design.  Be familiar with vocabulary and how to diagram experiments. 

The homework is listed below and the notes and investigative task are attached.

Notes - Experimental Design (2)

Investigative Task - Backhoes and Forklifts

HW - pgs. 312-315 (12-18 even, 33, 41)


Also, take a look at this video on ethics...good stuff.

Harvard - Course on Justice/Ethics

Experimental Design(1)

In class we finished up the section on sampling and did an activity on sampling.  We differentiated between a sample distribution (distribution of 1 sample) and a sampling distribution (distribution of many samples).  This led us to a discussion on the Central Limit Theorem which will play an important role during the second half of the course.

CW - Sampling Distribution

Afterwards, students were introduced to experimental design.  Students should be familiar with the following vocabulary words: factor(s) - explanatory or "x" variable(s), levels and treatments. 

The notes are attached and the homework is listed below.

Notes - Experimental Design (1)

HW - pgs. 312 (1-17 odd)
          read pgs. 301-309

**Quiz on Simulation, Sampling and Experimental Design - Thursday 11/20

Sampling (2)

In class we continued to talk about the various sampling methods.  Reiterated during this time was the difference between sampling error, or variability and sampling bias.  Sampling error is okay, it is bias that is the bane of any sample.  In class we completed the assignment below; complete and turn in if you were absent.


The homework is listed below and the notes are attached.

Notes - Sampling (2)

HW - pgs. 288-291 (8, 10, 12, 24, 26, 32)
        - Read pgs. 292-300 - Experimental Design

Sampling (1)

In class student learned about the 5 different methods of sampling.   Students also learned the difference between sampling variability/error and sampling bias.  Sampling error is okay as samples vary from one to the next.  Sampling bias is not okay as it renders the sample useless.

The notes are attached and the homework is listed below.

HW - pgs. 288 - 290 (1-11 odd, 15-27odd)
