| September 12 |
Read Sections 4.2 and 4.3.
Do 29 and 32 on page 113. (Ignore "mild" versus "extreme" outlier.)
Problem #1: At what percentile is Q1 if your data set has 105 points?
Problem #2: If you data set has 2(2m)+1 data points (for some m>0), at what percentile is Q1?
Problem #3: Make up a data set of 20 numbers that has exactly two lower outliers and one upper outlier (according to the 1.5IQR criterion). Draw a boxplot for this data.
Problem #4: Using the approximation of standard deviation from class, approximate the standard deviation for the data in problem 4.22 on page 109.
|
| September 14 |
- Do #19, 21, 22 (also approximate the standard deviation as we did in class) on page 109.
- Problem #5: Use your calculator to compute the standard deviation for the data in
Example 4.10 on page 110. What is the standard deviation if we treat this data as a sample? What is the standard deviation if we treat this data as a population? By what factor do these two answers differ? (i.e. What is the exact number that you have to multiply the sample standard deviation by to get the population standard deviation?)
- Problem #6: Order the 5 Statistics class (from the handout in class)
from most variability to least variability if variablility is measured by IQR. What if variability is measured by range?
- Make sure that you can use your calculator to find the standard deviation of both a population and a sample.
