=Data Collection & Communication - Felipe=

Counted data is always said to have an infinite number of significant figures (i.e. 10 people is the same as 10.00000000 people) so counted data will never diminish the number of significant figures in a final result. Measured data using analog devices must be estimated to one digit beyond the smallest gradation of the device. (e.g. Using a ruler with mm as the smallest gradation, you would estimate to 1/10th of a mm.) Measured data using digital devices will use the value shown on the instrument. (e.g. a digital thermometer accurate to the nearest 1/10th of a degree could read 18.3 C)

These decisions will affect significant digit, error and uncertainty calculations mentioned below.

=Significant Figures and Uncertainty at the OSCSS - Dave=

__Tests and Quizzes__ We expect you to apply basic rules correctly when manipulating data using a **single** type of operations (+, -, x or /). For more complex and/or multi-part calculations, apply a general rule of thumb to keep all intermediate work in your calculator and show a final result that has the least sig. figs. of all your source data (i.e. the rule for x and /). This is not fully accurate, but will allow you to focus on the content of the evaluation and not get bogged down with a concept that is more relevant to labs, assignments and "real life" work.

__Labs and Assignments__ Significant figures help you communicate the quality of a measurement. We expect you arrive at the correct sig. figs. for data you collect, as mentioned above. We also expect you to apply basic rules correctly when manipulating this data using a single type of operations (+, -, x or /). If calculations are more complex, seek guidance from your teacher, as there may be instructions specific to the task at hand. He/she will also give you guidance as to how to report and use values reflecting uncertainty, if this is requested.

Please note that, whether you are asked to consider uncertainty or not in high school, measurements and measurement processes have several sources of uncertainty and these would have a bearing on the reliability of any end result. As you move forward with work of more importance and a wider audience, you will learn more about uncertainty and consider it more routinely...if you want to be a good scientist!

=Significant Figures - Dave=

__Why are Significant Figures Important?__ Essentially, they help you communicate the quality of a measurement. https://www.youtube.com/watch?v=VAuslY-Uuf4&t=24s

__How Do I Know Which Digits are Significant?__ There are some rules that deal with the location of zeros in measured data. Remember that counted data is assumed to have an infinite number of significant figures, so these rules do not apply. https://www.youtube.com/watch?v=7b60RZqut0U&index=4&list=PLS-fCZtgwbl7ccSOqer1QfCzQQMAlNKs3

__How Do I Determine Significant Figures When Multiplying or Dividing?__ In brief, use the smallest number of significant digits of all your source data. https://www.youtube.com/watch?v=o5BmoMDJLRY&list=PLS-fCZtgwbl7ccSOqer1QfCzQQMAlNKs3&index=6

__How Do I Determine Significant Figures When Adding or Subtracting?__ In brief, use the smallest number of decimal places of all your source data. https://www.youtube.com/watch?v=2eXC6s9X6Wc&index=7&list=PLS-fCZtgwbl7ccSOqer1QfCzQQMAlNKs3

__How Do I Determine Significant Figures When +, -, x or / using Scientific Notation?__ All digits are significant in scientific notation. Adding or subtracting can be a challenge when the exponents differ. If you face this, it may be best to convert away from scientific notation, apply your rules and convert back. https://www.youtube.com/watch?v=IIQPHC5gZT8&list=PLS-fCZtgwbl7ccSOqer1QfCzQQMAlNKs3&index=8 https://www.youtube.com/watch?v=EKJSiM5guyA&list=PLS-fCZtgwbl7ccSOqer1QfCzQQMAlNKs3&index=9
