Lab: Analysing Experimental Data (Pg. 6 of Analysing Experimental Data)

ENTER your data here (Google Forms) for the frequencies you determined in each trial

SEE the data here. Copy and paste the data into a new spread sheet document in order to edit.

Using Excel: Calculate an average

Copy and paste your data into a blank Excel document (I suggest using column B so you can put your labels in column A)
Warning: Excel can be grouchy sometimes and thinks that you are pasting text not a number. If you get a weird answer click on your cells and see if a exclamation point icon shows up. If so click on it and select “convert to number”. The other option is make sure you copy the table from internet explorer and all should work fine.

Place your cursor into a blank cell

Type the command =average(B2:B?) Where “?” represents the last row your data is in… in this case it would be 12

Hit enter and there you go

Using Excel: Calculate Standard Deviation

Same procedure as the average calculation except use the command =stdev(B2:B?)

Exercise: logarithmic exercise

Inquiry assignment

Calculate the standard deviation for the nine trials performed during Friday’s investigation for the 10cm length only.
Approximately how many of the above trials should fall within the first standard deviation?
How many of the above trials actually fall within the first standard deviation? Does our data fit the model for standard deviation? Explain why or why not.
Using the logarithmic graph paper provided determine the relationship between frequency and length using the average for the frequencies for each length.

The general form for the equation is this. Solve for “n” using the log of slope from the line of best fit from the logarithmic graph. Remember to use only points that appear on the line of best fit.

Solve for “a” by substituting into using your value of “n” and any value for and that is found on the line of best fit.

The actual formula is defined as. Therefore the actual value for a = and n =-0.5

The ball just clears the top of the fence and heads for another building across the street. If Trump is 12 m from the fence determine:

a) The initial launch velocity (including angle) of the ball assuming he hits the ball when it is 1.0m above the ground. (clue: find your x and y components of the velocity first)

Inquiry Activity: Conservation of energy

Using the low friction air track we are going to compare the energy gain of mass 1 to the energy loss of mass 2

The low-friction dynamics car was placed on the elevated air-track. a small mass was attached to the car via a light string and the string was feed through the pulley.

The air track was engaged and the dynamics car was allowed to accelerate up the air track.

Using a stop watch, a metre stick, and the track markings the total height change, distance traveled, and time were recorded.

The final velocity of the system was determined and used to calculate the final Ek.

The total energy change for mass 1 and mass 2 were calculated and compared.

As a class, the discrepancies between the differences in the values were discussed and possible improvements to the investigation’s procedure were considered.
