What is the purpose of averaging measurements in evaluation?
To increase
reliability
View source
Why should a flowmeter be used in measurements?
It provides more precise
velocity
readings
View source
What does WWW stand for in evaluation?
What
Went
Well
View source
How do 50cm intervals affect reliability?
They reduce
bias
in measurements
View source
What is the EBI in the context of evaluation?
Even Better If
View source
What does the conclusion state about the Bradshaw Model?
Data
supports
it, but
anomalies
exist
View source
Where was the physical investigation conducted?
Sow Brook
,
Bilton
View source
What was examined in the investigation?
The
confluence
to the
source
of the river
View source
What trend was observed regarding velocity in the river?
Velocity increases with
depth
across the channel
View source
What happens to width and depth downstream?
Both increase downstream
View source
What model does the investigation follow?
Bradshaw’s Model
View source
Why was the site chosen for the investigation?
It had easy
access
and safe
depth
View source
What is a risk associated with the investigation?
Tripping
View source
What measures were taken to mitigate tripping risks?
Grippy footwear and
risk briefings
View source
What weather-related risk was identified?
Chill
and
hypothermia
View source
What precautions were taken for weather risks?
Wearing
appropriate
clothing and postponing
View source
What type of sampling was used in the investigation?
Systematic Sampling
View source
What is a disadvantage of systematic sampling?
High human bias reduces reliability
View source
How was depth measured during data collection?
Every 50cm with a ruler
View source
What is a benefit of measuring depth at regular intervals?
It reduces bias in measurements
View source
What method was used to measure velocity?
An orange floated down 3m of river
View source
Why was an orange chosen for measuring velocity?
It is biodegradable and easy to track
View source
What method was used to measure width?
A tape measure was used across the river
View source
What is a benefit of using a tape measure for width?
It is simple and accurate when taut
View source
What does a cross profile represent?
A drawing of the river channel at sites
View source
What is a benefit of using a cross profile?
It allows easy visual comparison
View source
What does a box plot show?
Max
,
min
, and
quartiles
of data
View source
What is a benefit of using a box plot?
It allows easy
comparisons
with other groups
View source
What does a bar chart illustrate?
Trends
between sites clearly shown
View source
What is a benefit of using a bar chart?
It clearly shows
trends
between sites
