Answer:
Length
function returns the nonnegative integer value. As an example, if we
enter: length (diag (5)):
>length
(diag (5))
[1]
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)

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.
Beautiful Rembrandts

Answer:
Length function returns the nonnegative 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.
