Learning Journal Reflective Comments:
Answer:
We
are in the middle of statistic course now. At this 4^{th}
week, I start with reading “learning guide unit 4” to get
understand about what statistic topics will be learned.
Then,
I write “discussion assignment unit 4.” After completion of
discussion assignment, I post it to the forum. Read other peer’s
posts, and give the comments.
Moreover,
I study the topics of fourth week that are the histogram, the box
plot, Median, first and third quartiles and the interquartile range,
outliers, the mean (average), Skewness, the (sample) variance and
standard deviation, and measuring the distance of a value from the
mean.
I
think have no problems to understand these topics. However, the
assignment unit 4 is quite challenging to complete.
