@@Vec135 Hey. That is super kind of you to ask! I am in the final stage of the Candidate phase. Thank you. I am praying by the end of the summer if all keeps going as it has so far. Sometimes life gets in the way, but it has been relatively smooth so far (minus the unceasing stress, anxiety, worry, and 0300hrs study times. Lol. No. That is all part of the program. It must be earned.) Thanks again!

Hi Matt is it possible to undertake a correlation where the sample size variables are different?

[@MattMacarty]

Thanks for your question. Pearson correlation is calculated using pairs of data points so the sample sizes need to be the same.

Hi Matt, how did you get the positive and negative variable you have there?

[@MattMacarty]

Those are based on a quick linear equation with a random error added in.

Thank you

[@MattMacarty]

[@jillianvelilia3064]

hello can I ask if where did you get the x and the none column. Because our professor only give us 2 samples

[@MattMacarty]

x is the independent variable, and the other three columns are examples of positive, negative and NO correlation. That's the one I labeled none. You can follow the link in the description to download the data file if that would help.

This is just showing the mechanics of correlation. p-value refers to testing correlation for significance.

[@ayaahmed7146]

if we compare the positive and negative correlation, the positive is stronger because its closer to one than the negative value (which is further away from -1)??? Right?

Yes

What if I have diff headings as 1 column had I'd no, 2nd one is ethnicity, 3rd one gender, 4 education level? And I wanna find corellation bw education level and gender then?

The process the same, only the column names have changed. You can also generate a table of correlations if you want: th-cam.com/video/DywVjSgkAR4/w-d-xo.html

Hello sir how to find correlation and significance value between environmental variables and diversity indices

[@MattMacarty]

The procedure for correlation will follow the demonstration in the video. To test for significance requires a longer explanation. There are a couple of methods you could use but it is not something I can explain briefly here.

[@komalbaig38]

From where we get positive and negative ?? Column?

[@MattMacarty]

I generated the numbers randomly. To get a negative correlation you use the first column and the column labeled negative. Make appropriate change for positive.

What is X referring to?

The variable on the x axis

[@maanajlan7056]

Is 0.222 is good relationship?!

[@MattMacarty]

So I wouldn't characterize relationships as good or bad. Maybe weak or strong or significant. The number in isolation doesn't tell me much, but I would presume that at the very lest this correlation is significantly different from 0.

[@nadk4448]

What would -0.249 be considered as?? Thank you

Weakish negative but likely significant
