compare sites
discrete data simply
interpret / construct easily

Answer 15

qualitative data visually
explains results
adds understanding

Question 16

What does a cross section show and how does it link to the enquiry?

Answer 16

compare width and depth
doesn’t fit with Bradshaw model
human management input

What does a bar graph show and how does it link to the enquiry?

Answer 17

changes in velocity
fits with Bradshaw model

Question 18

What does an annotated photo show and how does it link to the enquiry?

Answer 18

scale of river
sediment, vegetation, channel, floodplain

Question 19

To improve my data presentation I could have added…

Answer 19

….scatter graph

Question 20

From my fieldwork I have discovered that…

Answer 20

…velocity, width and depth all increase

Question 21

How did the secondary data help our understanding of the conclusion?

Answer 21

human interference altered channel in 16th century to provide water for Abinger Mill

Question 22

My fieldwork was limited because….

Answer 22

….only one day at site

Question 23

My fieldwork proved my hypothesis….

Answer 23

…to be correct

Question 24

The strengths of my fieldwork was….

Answer 24

….repeats taken
combined results - increase sample size
systematic sampling
stratified sampling
qualitative and quantitative

Question 25

I could improve my fieldwork by....

Answer 25

.... collect data from across year increase no. of sites increase repeats and no. of readings

Question 26

What was the hypothesis of my fieldwork study?

Answer 26

discharge increase with distance downstream

Question 27

Why would discharge increase with distance downstream?

Answer 27

velocity and cross sectional area increase - wider, deeper - transport/erosion

Question 28

What is the geographical theory which underpins this investigation?

Answer 28

Bradshaw model

Question 29

How did we avoid tics in long grass?

Answer 29

wore long trousers

Question 30

How did we avoid drowning and diseases from water?

Answer 30

- no drinking - no pushing - sanitise hands

Question 31

Where is the River Tillingbourne located?

Answer 31

between Dorking and Guilford in Surrey

Question 32

How does the River Tillingbourne's length make it appropriate location?

Answer 32

19km - can be seen over short time

Question 33

How does River Tillingbourne being local make it appropriate location?

Answer 33

return to site

Question 34

How does River Tillingbourne near to A25 make it appropriate location?

Answer 34

easy access travel between sites

Question 35

How does River Tillingbourne shallow and narrow make it appropriate location?

Answer 35

safe to study

Question 36

What are the 2 sites we visited called?

Answer 36

Crossways farm Abinger Hammer

Question 37

What is sampling?

Answer 37

data gathered on small part of population/area

Question 38

Why do we use sampling?

Answer 38

not enough time / energy / money

What is random sampling?

Answer 39

samples chosen randomly - equal chance of selection
