Data Tables - a method for organizing information (usually numerical) in a visual and easy to understand manner Required Elements All data tables should include… Title Headings with units Columns for the data Trials in separate columns Data to correct precision – same number of decimal places Required Element: Title All data tables should include… A descriptive title Includes the variables and what is being measured Usually this format: The Effect of _____ on ________. Example: The effect of heat on cricket chirp rate What is the IV and DV? IV= independent variable DV = defendant variable What Goes Where? Derived is another word for getting a value mathematically, as in an average. May be called Processed Data. Required Element: Headings Must clearly state the name of the variable (quantity or quality) the units of measurement (for quantitative data) What are the units? Variables? Air Pressure Height Basketball Bounced (cm) lbs/cm2 Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 0.5 1.0 1.5 2.0 2.5 3.0 Required Element: Columns Be Organized – The variables measured are presented in vertical columns by trial Basketball Bounce Height with Varying Air Pressure Air Height Basketball Bounced (cm) Pressure Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 lbs/cm2 0.5 1.0 1.5 2.0 2.5 3.0 Required Elements: Trials & Precision Columns contain the data collected (measurements) for each trial, recorded to the appropriate precision – the same number of decimal places. Averages must also be recorded to the same (never a greater) precision – the same number of decimals as the raw data. The Time Taken to Heat Apple Juice Time Temperature of Apple Juice (°C) (minutes) Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Average 0 32.2 30.3 31.0 29.8 30.4 30.7 3 41.4 39.9 40.6 41.2 39.8 6 68.3 69.2 67.1 67.6 68.0 9 86.7 88.1 86.8 87.5 87.7 12 94.1 94.0 93.4 93.6 93.1 15 99.0 99.1 98.6 98.9 99.2 Processed or Derived Data Tables You can include a column for processed data (mean or other mathematical process) in the same table but it must be clearly labeled as shown on previous slide. - or - You can do a separate table as shown on the next slide. Also clearly labeled. Example of a data table with the mean, labels present for all columns. Exemplars Your Turn 1. Calculate the mean 2. Create a data table for this set of experimental data, including the mean
