So, what are the differences? Start with Data: numbers, measurements, experiment results, quantitative observations, etc. Organize the data into a Table: data organized in cells and columns Finally create a Chart: a visual representation of data One type of chart is a Graph: interpretation of data – usually with 2 axes

DV Time to Complete Puzzle (s) Now, on to the present… IV Number of Hands DV Time to Complete Puzzle (s) A1 1 hand 354.2 A2 341.9 A3 328.5 xxxxxxx xxxxxxxxxxxxxxx B1 2 hands 208.9 B2 212.1 B3 206.1 Here is some sample data from the puzzle experiment. What type of graph would be best to visually show this data?
Now, on to the present… Since we are comparing two groups of trials, a bar graph is best to use.
Now, on to the present… To analyze the data and really see what is going on, it is usually best to calculate an average for each group. Average = add times then divide by # of trials.
A little practice… Calculate the average of 28 m, 32 m, 31 m and 38 m. 11 mL 13 mL 12.1 mL 9 mL 14 mL 9 mL and 13.2 mL Now, calculate an average of doing your puzzle the ____ way. Calculate a second average of doing your puzzle the ____ way.
Take a minute and create a bar graph from your puzzle data… Remember to give your graph a title. Remember to label the axes.
Now make a claim… Now that you have data averages from both the test group and the control group, you can make a claim. A claim summarizes what happened in the experiment then gives a scientific explanation why. Claim: The data show that a puzzle is completed faster with 2 hands than with 1 hand. This could be because one hand can be holding the piece for examination while the second hand is grabbing the next piece.
Now write a claim based on your graph. Summarize what happened. State a scientific reason why it might happen that way. Was your hypothesis supported or not supported?
