Geog2 AQA Geographical Skills 15th May 2015

Wait a sec, they put a question on the handout? Or am I reading this wrong?

Weird, Did anyone divide 2048 by 12? Which gave 248.75 for the mean? My standard deviation is really high (790) but I checked twice and I got the same thing.

Yeah I missed it. Apparently that was it and it was worth 2 mark. I'm just worried I missed more than one question..

I'm not sure about colouring in the trip lines, you'll probably be ok, at worst you'll maybe drop one mark.

The last question didn't ask you to refer to your data but I just dropped in my value of Spearman's Rank, but I'm sure it's fine if you didn't because they didn't ask you to!

I'm really not sure, but I think it would at most drop you to bottom level 2 (I think I had the opposite problem, I described how I did it but didn't draw conclusions as well as you).

For the quantitative and qualitative question I said that that qualitative doesn't have numbers and my example was an OS map to investigate the characteristics of the river. For the quantitative I said that it includes numbers and my example measuring river velocity which increased by 2.5 m/s. Is this right?

thank you. I was so worried my friend said I had to refer to the data which if you did i wouldnt have got like 3/8! Also, what did you write about spearmans rank? I had no idea but i wrote something like this:

I used spearmans rank to analyse my data by calculating the spearmans value using the median of my bedload data for each site. This allowed me to work out the significance of my data and whether it occurred by chance or not. Furthermore, using the significance level percentages (5 and 1%) it allowed me to determine exactly how significant or not significant my data set is and thus whether I should accept the null or alternative hypothesis (say what that are). Spearmans rank is a proven and reliable method of data analysis and so I was able to analyse my data in the best possible way.

Thats kinda what I wrote. What do you recon because i have no idea how it went.

For the last question could you have used a scattergraph as a method of data analysis as long as you talked about the line of best fit etc?

Yes. That's fine that's what I did, do you remember the wording of the question? command word was "describe" right?

For qualitative I'm mentioned looking at cross sections which were built to scale to see if they got bigger

Yeah it said outline one method of data analysis and the advantages. i don't think it wanted specific reference to your results?

So if I wrote about how I would do it as in what I put on the axis, drawing a line of best fit, removing anomalies and it was good to show the relationship easy to conduct and can be used with the Spearmans rank. Would that be right?
