You guys, does anyone know:
How can systematic sampling be used to chooses people to answer a questionnaire?

Thanks

I don't understand the first page where it says "void left... Filled by use of natural gas and an increase in electricity usage"

Can natural gas/ coal/ bio energy/ petroleum/ be used to make electricity, and if so why on fig p2 is it separated from these.

If not- what is electricity made from then?

Sorry if I'm just really stupid 😂👍🏻

yeah its pretty simple, systematic sampling can be used to select certain houses to send the questionnaire too. It is a method using every Nth number ( or every Nth House)

What does '‘energy efficiencies will continue offset population growth’ mean?

Investment in making buildings draft proof (using cavity wall and double glazing etc) and improving technology to save energy has led to better efficiency. As a result, the demand for energy has still stayed the same despite a growing population. Hope that helped :smile:

Bit of both: Unit 4B is an issue evaluation exercise and, as such, demands the development of the range ofgeographical skills, knowledge and understandingidenti ed in this speci cation. Unit 4B allowscandidates to extend the content of the speci cationwithin the specialised context of issue evaluation.

Ok... recommend anything that I can look at?

Like -
stand at the corner of a road at Blackpool (nearby major conurbation), and stop every 5th person that you see and get them to answer the questionnaire.

However, it's not the best method as they may not want to answer etc...

How do we answer the question Compare and contrast figures P2, P3 and P4 Also Can someone write in simple terms what the difference is in what they measure?

Yes. Choose the sites according to where residential populations are.
Then use systematic sampling to choose every 5th house to ask.
Hope this helps!

Fossil fuels are combusted to heat up water to produce steam to spin a turbine to generate electricity.

think that's how

Does anyone have any notes on Item 2 as i really don't understand the significance of it, or what i'd put if we were asked on it!

Using grid intersections on an OS map possibly? I think it'd be better to do random systematic sampling, were you sample at 500m increments with increasing distance away from the fracking sites (ie Roseacre). Essentially, youll have a radius of around 5km. At every 500m you could sample every nth house.

Hello! PLs could someone help me! "Discuss how the physical and social geography of Lancashire makes this an ideal location to undertake fracking.

Physically- Lancashire (quote from the map extract) is relatively flat which makes the area ideal for fracking as the flood plains lead to the largest aquifer in the country (meaning large water supply available). 5trillion cb m of marine shales to frack with estimated gas in the range of 18.7-51.9 tcm available to frack. 430 people per km which is high in pop density but that includes leeds, manchester, blackpoole ect, the actual area has pop density of between 50-99 therefore the rural area will not affect as many people
Social-Within 100miles of the North sea mining operation meaning skilled workmen with experience are in commuting range, high unemployement of 8% in NW of the country close to blackpool/preston large unemployment therefore talk about job opportunities, area ex mining therefore the manufacturing industry is already there. Close proximity to m6 making transport accessible.

Please add to it as my ideas are very broad

Disadvantages: If you're doing this during the day, people might be at work so no one will be at home.
Using grid intersections may locate areas that are sparsely populated or in a middle of a field.
People might not open doors for you. That's why a pilot survey should be conducted first to see which method of sampling is best.
I don't think there's advantages apart from having a set distance which keeps it fair and reduces bias?
