Mother and baby, painted by Rembrandt

1. Learning Journal Reflective Comments:
Answer:
This third week is a special week of the course, since we have the first “graded” quiz.

Reviewing all study material from previous weeks. Visiting self-quiz unit 1 and 2, and doing self-quiz unit 3. Then, Reading of learning guide unit 3.


2. Vocabulary and R functions
a) Enter the following command in R to read a simple help page about the length() command:
?length

What does the length function tell you?


Riding horse, painted by Rembrandt


Answer:
Length function returns the non-negative integer value. As an example, if we enter: length (diag (5)):
>length (diag (5))
[1] 25
Thus, the length function will return 25. It considers 5 x 5 with result 25.

b) Read section 3.4 about Measures of the Spread of Data. In your own words, give a rough description of what variance is (we will go into more detail in the next few weeks). Include an APA citation.
Answer:
The variance comes from the average of the square of the standard deviation. The standard deviation itself is how far deviated a value is compared to the mean of the whole set (Yakir, 2011)

Hebrew University. 


The beautiful view, painted by Rembrandt


3. Task
Estimate how many hours you spent on this class in the past week, then list the days and times when you will spend an extra 3 hours to study during week 4 and beyond. Units 4 and beyond often require more study than the first few weeks did, but if you prepare your schedule, you can improve your chance of success.

Answer:
If you feel left behind a little bit, devoting more time for next coming weeks. Learning 3 more hours on evening on each day, include weekends.
