I still can't believe my professor spent hours explaining what you just explained in 14 minutes!

This was really excellent. I work for a Hospital and I'm trying to determine likelihood of patients entering the ED. To your point, separate calculations would be needed for 1st, 2nd, 3rd shift and weekend vs week day and even holiday. Done well, it could give more insight to staffing needs. Good on you for posting!

They made this sound like rocket science. This is much simpler than i thought it was; you're great at explaining this!

[nesegumulcineli]

good stuff. would have loved this 30 years ago.

Excellent video. I'm currently doing a masters in data analytics and this video made it click for me.

[jemuelbjeroham]

I realized that this video was made in 2017 only when you talked about iPhone 7 🤣
Thank you so much... I preparing for my College examination through your videos.

[juliecongress]

You are elegantly clear and quite clever! I appreciate your manner. You make learning very friendly and fun. Thank you.

I was struggling to understand the Poisson distribution and this is the first video that made me understand it. Thank you so much!

[mitchelleze]

Very helpful...The way you present and answer the problems make them look simple and easy to follow.

[jenniferobrien]

Thank you, you just saved me hours of crossed eyes and tears staring at my textbook!

[christopherbarrett]

Nothing like the theory and then a practical exercise afterwards, bravo!

[lefttrade]

Cheers! Eventually someone who can explain it in a ordered and understandable way. I wish my uni would hire you for my stats classes... greeting from Norway.

Downright the best video on Poisson on YouTube

[lindaren]

Can you make a video about Gamma and Beta distribution as well?

[shagunsandhu]

Very underrated channel …
U are a heaven sent angel for anyone who struggles with stats due to boring teachers😂😂…(no offence to them tho) lol
Anyways, Thank you so much..!!!😊

[jimmyjones]

Thank you so much. Doing undergrad in math. Didn't like the statistics part of math, but these videos are helping me out a lot

Finally, I understand *why* the distribution of the photons we receive from a star (its flux) is a Poisson distribution. I realize that I have misconceptions about this distribution.

Thank you for this! Two quick questions: a) For question 3, Is it really fair/realistic to say that the average per hour is really 0.5 click sales though simply because the daily average was 12 in 24 hours? Is it truly fair to assume that every hour people are equally likely to order things rather than during specific peak/wakeful hours or is this all just hypothetical so that we can assume the distribution is poisson? And b) what if we don't know the mean?

EDIT: I see you addressed a! Thank you!! Feeling happy I understood the assignment haha

[akshaymishra]

Very nicely explained. Please also make a separate video on Poisson Process.

[nnezeht]

Excellent explanation!
I have a question regarding the bonus question though.

You said that the rate at which people are clicking on ads varies throughout the day, doesn't collecting an average of day-intervals eliminate that variation? meaning, only using Poisson distribution in the second question would not hold.
