SPSS - One-Sample T-test
We demonstrate how to run a one-sample t-test, including how to specify the test value for the parameter under the null hypothesis. We also walk you through the t-test result right up to the statistical and substantive conclusions.

SPSS - How to Insert a New Variable
Просмотров 14 тыс.11 лет назад
We demonstrate how to insert a new variable into an existing data file wherever you wish to have this new variable appear. For instance, suppose that between variables X and Y, you would like to insert variable Z. We demonstrate how to do this.
SPSS - How to Insert a New Case
Просмотров 4,5 тыс.11 лет назад
We demonstrate how to insert a new case into an existing data file. For instance, suppose that between cases 96 and 97 you'd like to insert a new case, that is, a new row of data. We demonstrate how to do this.
Understanding the Variance and Standard Deviation

This video is best viewed at 720 HD resolution, and even expanded on a large screen should appear crystal clear. At lower resolutions such as 360p or 480p, it is still viewable, though not as clear. UNDERSTANDING THE VARIANCE AND STANDARD DEVIATION: A brief lecture on the conceptual development of two very common measures of dispersion, the variance and standard deviation. We use a very small d...
Worth interesting.
What does it signifies if t value is negative
14:00
Thank you so much! I really thought I did something wrong when I saw all 0's as leaf values.
This helped me interpret the stem and leaf, thanks!
what is data that can be used in one sample t test
Never seen such a good explanation
dear friends how to find out Mean difference .... my calculation Test value-Mean value ....please guide me . in excel also
Too bad you no longer upload videos! Ive subbed to you anyway waiting for the time you resume making videos
Sexy Tutorial.
Superbly knowledgeable teacher! Bravo!
Best tutorial and thorough explanation I've seen so far. Very nicely explains what everything means, thumbs up!
Thanks love from india
What if the t-value is a negative one? If you can kindly clarify, thank you! :)
How do insert like a 100 defined variables in the middle of say a 4000 variable long data set? I basically took a few variables from another dataset and by creating new variables in the bottom of the new dataset where able to quickly create identical variables. Now if they were going to the top that would quickly be resolved, but it takes forever to move variables just a few 100 places so I have to create 100 variables 1 at a time which also takes forever or move them. Either way I'm screwed.
Thanks it's a good explain
Thanks it's a good explain
n-1
thanks a lot. this was really helpful
How can I test simple hypotheses (one independent and one dependent varable) in SPSS when data are collected in 5 point Likert Scale?
Is this the population variance? Sample is defined by the numerator is N-1?
this is the best explanation I've seen thus far. Thank you.
Great Video ! But I believe there's one correction: Starting at 18.10 of the video: "95% of Samples drawn from this population, this interval will capture the true population mean" Whereas the correct interpretation should be: ""95% of Samples drawn from this population, this interval will capture the mean difference between True Population Mean & Sample Mean"
very clear thanks
What a fantastic tutorial. Please do more!
This was extremely helpful for conceptualizing what variance and standard deviation are. I don't really comment on videos, but this was very well done. Thank you!
Many thanks
thank you... so clear and helpful...
Great !!!! Keep it up :)
Great work. This is one of the best explanations of a one sample t-tests I have seen. Also, it is one of the few videos which explains the "test value". Thank you!
Amazing. Very helpful, thank you.
Thanks for being very thorough in your lesson. Very helpful.
It`s very fantastic lesson thank you very much.
good but get to the point, you took 20 mins to explain something that could have taken you a max of 7 mins!
Yes! I got it ....NOW sheesh!!
