Z-Statistics vs. T-Statistics EXPLAINED in 4 Minutes

[@sidneyfrattinijr.9700]

I can not believe that you really explained it so clearly in a 4min video. Kudos, my friend.

[@AceTutors1]

Thank you so much for this amazing feedback. I sincerely appreciate you saying this

[@sherrymilligan-turner2999]

I agree, you really put it into real terms as to what we are doing in the big picture.

Your ability to condense yet still pull apart such complex topics is a true talent! I checked your stats playlist... I would love to see a follow-up going from here into probability testing in normal samples! T-statistic to T-test would be a nice transition 😊

[@doglife2447]

I'll be honest with you, my professor simply stated you used the Z-Stats when the mean is unknown and t-Stats when the mean is known. That's all he said!! I've been searching for hours to find the real difference until I came across this video. Thank you again!

[@xcissor_zw]

This is the most understable video on this topic KZbin wide

Taking a data analytics class and they're going really quickly over the statistics. This helped a ton. THANK YOU!!!

[@AceTutors1]

You are so very welcome! I'm glad we could help you out!

[@thunderstorm0826]

I’m a psychology student and failed statistics 1 once, passed next semester and then failed statistics 2 so I’m taking it this semester. It’s not that I’m bad at it but they just make it so dreadful. So glad I found this channel, I’m refreshing my memory from previous year and learning new stuff. Best of luck in everything and thank you!

[@inesz.3500]

I'm a psych student too and I'm struggling in my first statistics class rn. They move so fast and it's so much information!

[@2340-i9y]

dude i was trying to get this concept for a few months now, my mid is in a week and omg this saved me! Thank you so so much!!

[@austinb3560]

My man really simplified that so well. Thank you. My masters stat teacher is so bad at teaching. The more he talks the more confusing he makes us. Honestly, the undergrad teacher was better at explaining it than him. I wish she taught it. Also, that ending statement was comforting. I hate how a hard class (feels like it) can determine your future. That was reassuring.

[@AceTutors1]

I am so glad you found our content so helpful. It's stories like yours that keep us going. Thank you so much for your support.

[@that.unknown]

This is the first time in my entire life that I got to understand this concept. Before now, I just apply it without knowing what exactly it is about. lol quite embarassing for someone with about a decade of engineering experience and engineering postgraduate degrees. Thank you for making it so intuitive. This video is the best CPD I have done this year.

[@andrewhting]

Bruh, it was not too much information. In fact, It was all the information I needed to make everything click. Liked and subscribed as my way to say thank you.

tbh your video and other KZbin tutorials of hardly 5 minutes are way better than a professor teaching for 1.5 hr.

[@mahaylahelliott4965]

Thank you! Nice and simple 😊❤ also love the end quote

[@salonip4269]

You explained it so well! You could maybe add examples next time. That will make the concept clearer

Great idea! We'll make some example videos in the future!

[@이지형-w1f]

Thank you for explaining the difference between z-score and z-statistics. I've been wondering about that so much! I have a question: you said it's unlikely that we know the population's standard deviation. But how would we know what the mu is then which is the population mean?

[@miayashin8686]

exactly what I needed! thank you.

[@ashishkumarmajhi4750]

Great video

[@Lucid874]

2:08 I dont understand in what scenario I would not know the population standard deviation when I know the population mean. Could someone explain this to me please?

[@gustavomontecinos2474]

You don't. What you have to do is assume the mean population. Since you have the other parameters you can sa for example, let's assume the mean population is "2", then you fill the rest of the formula and you are going to get the cumulative probability of that happening in the population. In summary, your mean population serves as an "X" that you can replace to see what's the most likely value, or better, the most likely interval.

[@ahmadabdul7807]

[@AceTutors1]

You are so welcome! Thanks for watching!

[@accgarage2663]

Very helpful. Thanks!

[@grhodes29]

Since you have to get the population mean in both and that can be difficult in many cases, I don't see how the t stat as any more valuable. You have the population mean in either z or t stat, getting the population SD is trivial. t stat would make more sense if you didn't have to have the population mean.

[@topmodelgardley3462]

Thank you so much for this video. I watched several other videos and read so many examples that did not help me comprehend this concept at all. I was trying to get an understanding of the z-score and t- statistic but I received so much more from this video. Remembering various formulas is difficult for me but actually understanding a concept allows me to make meaningful connections amongst criteria. Thanks again! I can finally move to my next problem phewwwwwww!

In z-statistic sample meam is rundom an mi (population mean) is knowm, but in t-statisic sample mean is known and mi (population mean) is rundom value.

However, for n bigger than 30, whenever pop SD is unknown, it is recommended to use the z-table and not the t-table (according to Google). Can you explain or refute that?

[@gurnoorsingh7469]

I have a question if population standard deviation and sample standard deviation both are given then what to do ? what to take z score or t score please reply i have exam in 2 days. really appreciate your work.

[@AceTutors1]

I recognize this is pretty late, but if they give the population standard deviation, I would recommend using z's

[@SkyRiderJavelin]

should use standard Definition so your content is accessible to all especially when chrome casting over wifi

[@AceTutors1]

Thank you for the suggestion! I think you can adjust the video quality on your end with the Settings button below the video. That may help

[@samkab677]

Can these be done in NON parametric tests Can these be done in non normally distributed data?

[@SoumayaBoussaha-b3y]

can we interpret those probabilities of the normal distribution using the empirical rule like for exemple if we get a probability equal to 97.83%, we fo a approximation?? i hope you answer this plz!

[@ambroshdev7737]

If n is greater that 30 and population standard deviation is unknown then can we use z statistic?

[@AceTutors1]

Great question! When n is greater than 30, it is often a fair assumption to be able to use the normal distribution, AKA the Z-statistic

[@Sir_Phuzy]

What if sample size is large but population standard deviation is not known?

[@Samanananananan]

Okay I won’t let a class get in my way 🥹
