• Variability
• Quantify the spread of data using the range and standard deviation.,Identify outliers in data sets using the concept of the interquartile range.
• Standardizing

Pushkar Dk completed this course and found the course difficulty to be easy.

A lot of people here have found this course boring. I think it is slow paced so that anyone can easily understand the material. In my opinion, there are enough quizzes and exercises to keep our minds occupied and it's not boring!

The way things have been explained in this course, both according to visualization of variables and the use of real-world examples, has been excellent!

This course lays the foundation for another course on Udacity called `Intro to Inferential Statistics` and that course has been rated very high on Class Central which is why I think *this* course is important.
• Lukas Tencer is taking this course right now and found the course difficulty to be easy.

The course is quite boring. Lets you perform boring counting and numerical tasks with little focus on actual statistics. Though, by the end of the class things improved. There is at least one serious error in exercises, where you have to answer question on factual data provided on previous slide and have to go there and back between 2 slides. Also some concepts are mentioned and used early in the class but introduced only later on. I miss more mathematical derivation of formulas e.g. SE.
• Farsan Rashid completed this course and found the course difficulty to be easy.

Pros :
# Starts from the very beginning of statistics
#Introduces most fundamental concepts of descriptive statistics
#This course is a part of Nanodegree (Just like specialization in coursera) and pushes you on the track of next course which is inferential statistics

Cons:

#Boring course with unnecessary videos and countings. May be instructor tried to make the course too easy but it made the course unnecessarily lengthy.
• Deepali Karmali completed this course.

It was good revision of everything. All concepts and formulas I had forgotten over a period of time. Looking forward for more such courses. It took me less than a month to complete the course. The instructor is very clear with her explanations.
