4.2622E-217 is an error, you have too many decimals. try doing the calculus on a piece of paper, replacing and estimating the decimals with 10 to -1 (-2, ...-n power) or positive power depending on your calculus.

[Medivh02]

TY man, you saved me alot of research +1

[127kawaii]

ummm im trying to do this but i have vista format of excel...so can you help me?

[Marluvvy]

My Excell doesn't give me a TSTAT option, only TTEST, TINV, and TDIST?

[rwinters123]

@Marluvvy

TTEST is the one you want to choose.

[Northwinde1]

I don't usually comment on videos, but felt I had to thank you, best explanation I've ever had! Thanks!

[samwinstanley73]

Great explaination, the best I've seen having worked in market and social research for 20 years.

[k1k1o7e1]

hey i cant find data analysis in the add-on list can you tell me where it is?

[drprettyboyhot1]

hey this is great and all but can you do one with unequal amount of numbers please

[rwinters123]

@drprettyboyhot1

You certainly can, When you select the ttest function, it asks for 4 things. The first two things are the number arrays. It's ok if they have different amounts. The third thing it asks for is the number of tails. Select 2 here. The fourth thing it asks for is the type of ttest. Enter in "3" here. This is for unequal variance.

@rwinters123

thank you and this is the same person just a different account

[jennyinwaiting]

Why do my results make no sense? I'm getting things like 8.2234E-18

[rwinters123]

@jennyinwaiting

Your results make perfect sense. The ttest number you got is just very low. many decimals worth. This means your two sets of data are very different.

[shazzaforeverthabest]

THANNK YYYOUU SO MUCH!! My bio teacher is a dunce, so thanks again. Only question i got is what is what is the results of the t test? My question in the book is literally"Results of t-test for our set of class data". My p value was .37, so i put that number down and said no statistical difference between the 2. Is that right?

[bloodysalope]

Thank you for this great explanation. You should give stats course.

[tehtrusmartguy117]

Really breaks things down if you never taking a stats class. Great Job!

I got an e value of 4.2622E-217; Was a massive data set. What does this mean?

[rwinters123]

@Castrophia1986

It means the two sets of data are very, very different.

[gerardobrenes]

[1hottiewife]

Thank you for this video. Your explanation was thorough and precise.

[cutycake]

Than you so much!

[donolie21]

Thank you much, this video was a great help :-)

[ppumpk1nh3add]

if we have two independent sets of data shouldn't we have used an f test first to check if their variances were equal before deciding which t test to use?( unequal variance or equal variance)

we don't use the F test when we we have paired data because it's the same individual right??

[rfiema]
