Despite being an 'old' video, it contains valuable information that everyone can benefit from. Thank you for sharing

[@asmaawasfy3150]

its the simplest explanation i fond in the internet thank you

[@maryobourgyimah8638]

Couldn’t agree more

[@prasshanthvp1082]

Exactly what I needed. Simple and much better than other statistic explanation on various time series plots. Thanks a ton :)

[@ThePoptartjunkie]

Love the explanation! Great to see your personality coming through as well! Really keeps one interested in the content! Thank you so much!

[@anoopjs03]

you should be an inspiration to so many teachers!!

[@further_maths]

Thanks! Glad you like it - and thanks for commenting :)

[@sidney6522]

Sometimes a simple explanation can be more efficient than academic language. Thank you. Every teacher should be aspiring to you.

[@ishrat_eva_14]

One of the best videos in KZbin 💥💥

[@user-gq2eq4gw2k]

I hadn't found such excellently explained video till date for stats. I have an interview into the data analytics field and this helped me understand and apply time series charts so well for whenever I use it in Tableau. Hope to see more coming :) I would love to follow you for my Data Analytics learning journey.

[@mchras]

I rarely comment on these types of videos, but now I just had to. I have my exam next week and this video taught me more than a chapter of 50 pages and 2 lectures did. THANK YOU!

[@further_maths]

@Jordan - thanks man. you're very welcome! i'm really glad to hear the videos were helpful in studying and putting together your notes. that was the aim!! Good luck on exam 2 tomorrow!! Cheers

[@jordandoddridge]

thank you soooooooo so so so much, ive used all your videos for my exam summary book, and learnt heaps, saved my life

[@rikiakbar4025]

Simple explanation, very intuitive, examples available. The best introduction video to time series by far

Fantastic...I was in a trough but you pulled me to the peak of understanding of a time-series....thank you very much...

[@ashutoshsingh7529]

This helped me a lot. Thank you so much !! Finally I can tell the difference between seasonlaity and cyclicity. Thank you for explaining those in-depth. Appreciated the questions as well.

[@EnglishCareerCoach]

Really helpful! Thanks a lot

[@RajeshKumar-ty5bm]

Simple and Nice

[@RayRay-yt5pe]

Oh my God! Thank you!

[@further_maths]

Hard to know without seeing the graph, but it that distribution sounds seasonal yes

[@sunnylk6991]

Thank you!

[@nolramlaredam]

Hi! is it seasonal when the peaks is at the same time interval but the troughs is not in the same interval sometimes?

[@lourdesmartinez1486]

Hi! Thank you very much for this great video :) I have a little question about the "Random" sample (minute 10:30)... I understand that there is a single peak in the series, however this could be noise? Then the remaining series could be analyzed separately and in such a case find some pattern or regular behavior? Thanks a lot for your answer!

[@maxscene7]

Can I just say-- other than the awesome explanations, the writings on the screen is so fucking satisfying to look attt

[@0055here1]

excellent

[@scalpmaster]

I am trying to analyse a past series of numbers that oscillates between 107 & 210 with a normal frequency bell curve distribution of mean 162. What is the way to extrapolate/project short term future range for a trendless but cyclical time series?

[@hayatullah3135]

the way she speak "Monday".. respect from pakistan

[@gudrunrumpf2987]

thank you

[@jeandelorstuyishime3130]

Hi, thank you for the explanation. I’m still a little confused between cyclic and irregular fluctuations as some of the graphs I saw looked irregular but they were cyclic! Can you tell me how I can distinguish between the two?

[@miguelangelsanchez5959]

Seems like American English speakers pay too much attention to the pronunciation rather than the real stuff. Typical American PATTERN. Excellent explanation. Thank you for posting.

[@sudeshnadutta5702]

Hey, when you say (around 18:30 mins) that the it does not have fluctuating peaks and troughs that is variation , relative to which line are you saying that the variation is less? I mean how do we calculate the rolling variance here?

[@gamerdude6125]

15:05 i think the average snowfall graph has more of a negative trend pattern but it is cyclic because the peaks and troughs aren't happening over intervals of time

[@raedos1]

Yeah her estimation of negative/positive trends is quite off sometimes

[@quentin8651]

I would rather pay you tuition than my stats prof......thank you!

[@nri2908]

What if actual and predicted start from different scale or has a wide difference in their starting point

[@further_maths]

@linrulezzz Yeah that's a tough one!! A whopping 50% of students taking that exam said the answer was D, with only 39% of students correctly answering E. I think the "only" part put a lot of people off, because it looks like it has some sort of variation, probably cyclical, given those peaks and troughs. But that's not one of your possible answers so you just have to go with the one that makes the *most sense*. Can you see how its definitely not seasonal though? Bastard of a question!! Hehe

[@further_maths]

Haha I know, I know, I'm such a dork... I get excited about the weirdest things. But you got my point right? Hehe. now every time you see a peak I hope you're thinking - "MONDAY!!!"

[@ibrahimmalik6897]

Further Maths your very nice and your video was very helpful god bless you

[@Berghiker]

What if a few days are skipped in a row and no data has been entered? Will it still present a time chart from the first day and then the next after the skipped days?

[@Berghiker]

How do you connect uneven spaces between dots on a line chart? Is this possible with excel?

[@thepresistence5935]

3:34 Definitely I got feared 😂😂😂

[@farukhzunaira]

Thank you mam from Pakistan 🤩

[@linrulezzz]

the last question fooled me! haha

[@MyLenscape]

have a question, how to determine the graph has positif or negatif trend? by formula and not by eye visualize

[@asmaawasfy3150]

do you have another video in time series please put the link

[@stradegy3338]

Why did you stop making videos? It's been ages! give us a re-visit.

[@Potzakv20]

i dont get it, where is saturday and sunday

[@kenn756]

Are seasonality and cyclicity mutually exclusive?

[@pascal3934]

I love MONDAY!

[@jayoungwong4116]

this video is great, but wtf is a doona?

[@jacobdichter5871]

Who the heaven says secular. why not linear? Great video
