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