[@Raapadap]

I just purchased a 2019 mitsubishi outlander sport with 34k miles and now I cramming to study for my quiz. I was really confused about what T score meant and you really made it clear to me. Thank you for your knowledge.

@@keenchie I now have 71k miles on my 2019 Mitsubishi Outlander Sport. It is a base model that is colored red. Everything from the feel of the steering wheel to the turn signal to the click of the seatbelts makes me feel exactly how I felt when I passed my quiz thanks to this generous man and his video.

Thanks a lot sir, but I still didn't understand how you calculated the z score.

[@tj6767]

okay but how do you get the -1.30?

[@Saradrakee]

Ok so a Tscore of 42 out of 105 questions, how many questions would you have to get right? Confused 😕

T Score does not work like that.
The range for T-score is generally 0-100.
The range for z-score is usually -4 or -5 to +4 or +5.
Then you have the mean, which for example could be something like 100.
And then you have standard deviation, which could be something like 15.
So, each standard deviation corresponds to a z-score.
So, if your value is 85 when you have a standard deviation of 15, then the z-score will be -1. If your value is 130 then your z-score is 2.
If you use the t-score, it will have a different standard deviation value.
For example, a t-score value generally ranges from 0 to 100 so that you do not have to deal with negative numbers in your calculations.
So if you look at your median value of 100 on your graph, this will correspond to a t-score of 50. 50 is in between0 and 100.
If you have a value of 115 or a z-score of 1, for standard deviation 15, then your t-score will be 60.
If you have a t-score of 30, then your value on the graph would be be 70 for standard deviation 15.
For the same value in z-score it would be -2.
The main advantage to using t-score, is so that you do not have to use negative numbers in your calculations, but there are also other reasons to use t-score.
