Let's say that group A runs an experiment to calculate density of an object and gets a value of 10 g/cm^3 with an error of .005 g/cm^3. Lets say another group (B) uses a different experimental technique to measure the density of the same object and finds a value of 8.2 g/cm^3. Did group A do a better job than group B? Make sure your answer includes how random and systematic error played a role.

Let's say you did this part of the experiment and you obtained the following information: - You used 0.192 g of unknown acid for your titration. - It took you 26.42 mL of 0.05 M NaOH to reach the equivalence point. - The pH at half-equivalence point was 3.18. Questions: 1. How many moles of NaOH were required to reach equivalence point? See your lab manual for help (page 97). (2 points) 2. How many moles (or equivalents) of unknown...

1) We use this formula: [Experimental value – Theoretical value]/ [Theoretical value] to calculate: Group of answer choices Atomic decay Biased Error Relative percent error Efficiency Redshift 2)You measure the diameter of a cylinder 5 times and get five different values (d1, d2, d3, d4, d5.) Then, the average value would be: Group of answer choices (d1 x d2 x d3 x d4 x d5) divided by 5 (d1 + d2 + d3 + d4 + d5) divided by 5...

JAVA MASTERMIND The computer will randomly select a four-character mastercode. Each character represents the first letter of a color from the valid color set. Our valid color choices will be: (R)ed, (G)reen, (B)lue and (Y)ellow. Any four-character combination from the valid color set could become the mastercode. For example, a valid mastercode might be: RGBB or YYYR. The game begins with the computer randomly selecting a mastercode. The user is then given up to 6 tries to guess the mastercode....

Summarize the experiment(s) and answer the following question:
Why is this a correlational study and not an experiment (hint: why
can't researchers manipulate the independent variable here)? What
do you think of their measure of charisma and social skills? Why do
you find it satisfactory or unsatisfactory?
