Thank you so much, this was cover-work and at first glance it appeared to be impossible but it turns out with your assistance it was quite simple. Thanks again.
Hi, when you use the critical values table, do you use the degrees of freedom based on how many values there are that you're measuring the correlation between?
Yes, you can either rank the highest value as 1 or the lowest value as 1; the answer will be the same. If you choose to use rank 1 for the highest value in that column, then you must also use rank 1 for the highest value in the other column.
Thank you. I think you mean the final Rs value (final Spearman's Rank result) rather than the d value in your question? If the Rs value is negative after doing the calculation, then ignore the negative sign initially and follow the same rule for looking at the significance table as if it was a positive one. If you are then able to accept your alternative hypothesis then your results would indicate a significant negative correlation between your two variables.
In this example degrees of freedom is correct i.e. 12. Most texts point to n = pairs of data, although a very few do refer to n-1. I use the both the Geographical Association's "Methods of Statistical Analysis of Fieldwork Data" and the Royal Geographical Society's "A student Guide to the A level Independent Investigation" as sources for my stats teaching and videos.

bonkers video. helped my little pogchamp son with his geography coursework
Now this is poggerz
Very poggerz

What a legendary comment
Got a geography assessment in 10 minutes! Completely forgot what this was, thank you sooo much! It was super clear!!
Much appreciated! I totally get it now. In note form, it looks so daunting
I've never seen or heard of this before but thank you for being so clear :)
Thank u so much Mrs. Spicer, I really needed to understand this for my A Level Geography exam! :)
Thanks this really helped. Always hated revising over this area of tectonics but it all makes sense now!
you've explained this so well!
Thank you Mrs that was a good video
I'm quite confuse whether I should use spearman or magnitude. Since in pearson we can say that if magnitude increases no. Of deaths also increases
The graph only helps to decide if a stats test is needed. It's not part of the stats test. Good luck with your exam.
Hi, when you use the critical values table, do you use the degrees of freedom based on how many values there are that you're measuring the correlation between?
Or in other words, how do you know how many degrees of freedom to go to?
hi. if you could reply asap that would be great. exam tomorrow :O does the graph have any relevance ? Or is the table all you really need
My teacher said to rank magnitude as 1 being the highest?
Yes, you can either rank the highest value as 1 or the lowest value as 1; the answer will be the same. If you choose to use rank 1 for the highest value in that column, then you must also use rank 1 for the highest value in the other column.
thank you mrs spicer
Please help!! Mid geography lesson and we have 3 of the same?! What do we dooooooo
wow great explanation!
Can you still count from the biggest to smallest from 1-12?
Yes you can, but you must do this for both columns when ranking.
@@mrsspicer4578 ok Thank you so much
Thank you so much!
Hi! Thank you this was very helpful. I'm just wondering, do we need to memorise the formula for the AQA A-Level exam?
No, fortunately you don’t need to memorise the formula for AQA A level. You’ll need to know how to interpret the result only.
Thank you so much, amazing🌟
Thank you so much this is a massive help
Amazing tutorial! What would you do regarding significance levels if the d value was negative?
Thank you. I think you mean the final Rs value (final Spearman's Rank result) rather than the d value in your question? If the Rs value is negative after doing the calculation, then ignore the negative sign initially and follow the same rule for looking at the significance table as if it was a positive one. If you are then able to accept your alternative hypothesis then your results would indicate a significant negative correlation between your two variables.
Needs to be (n-2) which is 10 degrees of freedom
In this example degrees of freedom is correct i.e. 12. Most texts point to n = pairs of data, although a very few do refer to n-1.

Tysm
thanks cheers for the marks brother xxx
degrees of freedom for this example would be 11, not 12. as df=n-1. (the example still works, in this instant however).

Mrs Spicer okay, thank you :). We use n-1 for our course.
who's here from Miss Cothams Geog class
me
Thank you so much
Life saver
Miss u a sket
Can't blame her, she just wants to spice things up
hero
thank you
In the exam is it shown that it's a spearman's rank
