Welcome,

[@gablvrs]

kung correlational, bakit po may pre and post test?

[@angelitobalboa412]

hi Sir! Tanong lan po.. I have two groups (control and treatment) and both of them will undergo pre-test and post-test. What test should I use to know if there is a significant difference between the two groups? Thanks!

[@glentox1563]

Hi, thanks for asking. Please use the T-test for Two paired samples.

Hello, Goodevening po. Ask ko lang po kung paano po nacompute yung sagot na 3892.86 into manual po. also the second r po. yun na lang po kasi ang hindi ko ma gets. thankyou po

[@dhaisynebreja4284]

sa test-retest po ito

[@glentox1563]

Hi, thanks for asking. Here is the interpretation of the formula.
3892.86 = Sqrt((15*30817 - 677*677)*(15*30184 - 670*670))

Hi Sir. If you're going to get the PEARSON R manually, pano po?

[@glentox1563]

Hi, thanks for asking. The video is already a manual computation. It was done fast because it was done in a spreadsheet. It will take you longer time if you use a calculator.

[@JhonMichaelRiño]

ung x and y po ba ay raw score sa test??

[@glentox1563]

yes, for test-retest, x is the score of the first administration of the test. y is the score of the retest taken after a certain period of time.

[@capacionikkimaeg.7974]

Ano po yung function code ng RANK sa Excel?

[@glentox1563]

Hi, please check the video. I just showed it in the video.
