Answers to Guide Questions:
1. To determine closeness or conciseness between data values.
2. To determine if the data values acquired during experimentation can be considered as a valid result.
3. To determine if a questionable data value can be considered a valid data value used for computation.
4. Statistical analysis from set 2 is more accurate due to having more trials, making the margin for deviation smaller.
5. To determine the closeness or conciseness between data sets
6. Types of Error
a. Systematic – problem with equipment resulting to error
b. Random – Temperature that can affect the results and calculations
c. Gross – breaking a set-up halfway through the experiment
7.
8. To avoid oils or liquids from the experimenters’ hands from making contact with the coins, adding mass to the coins, making the measurements inaccurate.
9.
