ON YOUR OWN ANSWERS
1a) Yes, it is a statistical question because you would expect the ages of people who retire early to vary.
b) Cluster around 60. Peak at 60 and two gaps, one between 56 and 58 and the other between 62 and 64.
c) Most people who retire early are about 60 years old.

2a) 20 students ran the race (there are 20 data points)
b) You can collect these data with a stopwatch. The units would be seconds.
c) Question: "How long does it take a sixth grade student to run 100 meters?" Answer: It takes most sixth graders about 13.8 seconds to run 100 meters.

This video is an introduction to statistics. We discuss what exactly the study of statistics is, the different steps involved, and how we can use certain measures or data displays to help explain a set of data. We talk more specifically about identifying statistical questions, making dot plots, identifying clusters, peaks, and gaps, and interpreting that information to answer a statistical question.

This is the most transparent style of teaching because this mans' personality is so gentle yet very enthusiastic. His parents must be so proud of him.

You’ve just eased all my worrying for this upcoming semester in this video. Thank you soooo much!

[Mr.Restituyo]

Great job. Another word we use for teachers is facilitator, which comes from the Latin word, "facilitar" which means to make things easy to understand. You are a great facilitator. You make things so easy to understand. Congratulations.

For the last problem I got:
A 20 students total.
B peaks: one peak at 13.8 (5 students)
Gaps: found between 13.0 and 13.2
Clusters found around 13.8
And my statistical question would be:
What is the average time for these 20 students in a 100 meter race?

I truly appreciate the way Mr. Jacobsen explain statistics ... he makes it seem so simple

[aercastro]

Statistics may not be easy for those who are not good at math and formulas.
It all depends on the person. Is not impossible but it may take a long time or short time to understand.
If you are in college, you need to understand statistics really fast.

The weight of "a" mouse is not a statistical question, it is a sample question. What is the weight of mice? That is a statistical question that requires you to weigh more than a single mouse.

I have been thinking lot of my upcoming STAT class since most of ppl saying it’s difficult course.After this video you changed my mind and you really motivated me to take the class. Thanks for the great video and I hope you post more about it.

[carlosdorothy]

I wish you are my teacher. You made me love maths by the way of how you explain it! I have to self study because my teacher doesn't teach us anything. Thank you for this! So useful.

[onkila]

I did subscribe, I loved the simplicity of your explanation. I'm about to take a stats class in college and i wanted to get an idea about stats before taking it. I hope my professor will be as good as you are :)

[katiewilson]

I have this class for my next term, it helped me understand what I am going into! Thank you so much I am not as worried anymore, I got this! 😃 😊

[iannagiddens]

This was very helpful because I’m starting statistics in my first semester of college in the fall❤

[DanzEnglish]

I wish you were my teacher. Your explanation is so simple yet easy to understand.

[LimAragon-oxtk]

Actually, I gratuated from old curriculum at philippines year: 2014-2015, now, I try and praying. because, I have a desire to study again to have a profession but I'm afraid to enter cause of many hard teaching and topics, even in assessment I don't know if I pass it or not😢😢 May the Lord have mercy on me and give me wisdom and understanding about this one!

[reneeb.]

Wish all instructors were as thorough as you. In class, it seems instructors are intentionally vague. Excellent delivery, the cream rises to the top!

[michellerehman]

OMG! I was always scared to take Stat class. However, after watching your video, I think I can do it. Thank you so much. I will try to go through your lectures and practice problem solving before taking a real course. ♥️♥️♥️
