Cley Hill Flashcards
What was the title of the investigation?
Investigation into the effect of relief on microclimate, Cley Hill, Warminster
What were the two hypotheses?
As altitude increases, temperature decreases
As altitudes increases, wind speed increases
What does SMART stand for?
Simples Measurable Achievable Realistic Timed
What kit did we use to measure Altitude?
Altimeter
What is the problem with altimeters?
Slow to update
How did we solve the slowness of the altimeters?
Teachers went ahead of the group
How did we measure exposure?
Clinometer and compass
What were our problems with clinometers?
The horizon was blocked by foliage and people struggled to find North
How did we measure slope angles?
Using clinometers
What was the issue with clinometers?
Relied on same height
What did we measure air temperature with?
A whirling psychrometer
How did we measure wind speed?
Ventimeters
What were the issues with ventimeters?
Got quite gusty, making the determination of scale hard
How did we solve the issue with ventimeters?
Made it same time as psychrometers to reduce mistakes
How did we check our data?
Used Met Office data and previous groups to see previous trends
How did we present our data?
In a spreadsheet in Excel
What type of graph did we use to plot air temperature against location
Bar Chart
How did we analyse the data?
Measurements of central tendency
Statistical Tests
What are the three measurements of central tendency?
Mean
Median
Mode
How many sites did we use?
12
What were our intervals between sites?
20m
Which sampling strategy did we use on Cley Hill?
Systematic sampling
Why did we use systematic sampling on Cley Hill?
It gave us an even spread across the hill
What were the four pieces of equipment we used?
Pentameter, whirling psychrometer, gun clinometer and a compass
What was one problem faced using the equipment?
We didn’t have enough gun clinometers between the different groups
How did we improve the reliability of our data?
Replication of data collection
Pilot Survey
