Continued with 3.3 Bernoulli trials. 

HW: look at questions towards the end of this section.
For the next few days Ms McGuinness will be revising Probability chapter 1

After correcting HW on expected value we looked at Bernoulli trials (Binomial Distribution)
HW: Ex. 3.3 Q.1-6

Probability Chapter 2
Today  we looked at 3.1 Tree Diagrams and introduced 3.2 Expected Value.
HW: Ex. 3.1

Today we looked at Q.19 from 2.5 Measures of Variability. 

We then started 2.6 Stem and leaf plots  (stem-plots).
HW: Ex. 2.6 Include Q.5 and 6

Today we looked at 2.5 Measures of Variability. This included:

• Standard deviation on calculator
• Range
• Quartiles and Median
• Inter Quartile Range (IQR)
• Percentile rankings

HW: Work through questions in Ex. 2.5

Today we returned the tests on chapter 1 and then looked at: 

• Mean, Mode, Median, 
• Outliers
• Which average to use
  
• Mean of a FDT and GFDT
• Using the calculator to get the Mean 
• Using the calculator to get the Standard deviation

HW: Standard devaition question from Ex. 2.5

Reviewed sampling methods video and definitions in yesterdays blog.
Introduced 3.4 Mean, Mode and Median.
HW: Try questions from 3.4
