Data presentation

• What is the first step after completing fieldwork data recording?

  Collate the data into a suitable table
• Why are tables used in data presentation?

  They allow easier graphing and trend identification
• What do tables aid in during data analysis?

  Describing trends, patterns, or anomalies
• What is the purpose of graphical techniques in data presentation?

  To allow easier visual interpretation of trends
• What are the essential components for appropriate graphing?

  Title, conventions, accuracy, and method
• What does the 'T' in the graphing acronym stand for?

  Title naming both variables being plotted
• What does the 'C' in the graphing acronym represent?

  Conventions like labeled axes and units
• What does the 'A' in the graphing acronym signify?

  Accuracy in plotting data from the table
• What does the 'M' in the graphing acronym indicate?

  Method appropriate for the data displayed
• What two variables are being graphed in this investigation?

  Soil pH and distance from the shoreline
• What is the aim of the investigation?

  To investigate changes in sand dune characteristics
• What is Hypothesis 1 regarding soil pH?

  Soil pH decreases with distance from the shoreline
• Why is a scatter graph appropriate for this data set?

  It shows the relationship between two variables
• What should be plotted on the x-axis of the scatter graph?

  Dune crest with distance inland
• What should be plotted on the y-axis of the scatter graph?

  Soil pH
• What should you always refer to when answering questions about the data?

  Our data sets
• What are the key components of a scatter graph?

  • Title indicating both variables
  • Labeled axes with units of measurement
  • Accurate data plotting
  • Appropriate method for data type
• What is the title of the graph to be created?

  A Scattergraph showing soil pH
• What does the x-axis scale represent in the graph?

  1 cm for each dune crest
• What does the y-axis scale represent in the graph?

  1 cm = 1 pH
• What are the components needed for a successful graphical presentation in fieldwork?

  • Title naming both variables
  • Conventions: labeled axes, units, consistent scale
  • Accuracy in data plotting
  • Method suitable for data type
