~LAB 1~ - (ANSWER)~LAB 1~
If you are using the Logger Pro interface to find the average value of some data, the fastest way to do
this is to highlight the data you want to average and use the ______________ tool. - (ANSWER)Statistics
If you are taking measurements of a quantity that is constant and you get 10 slightly different values, the
best way to analyze the data to get an estimate of the quantity's value is to - (ANSWER)compute an
average of the 10 values
Comparing the two data sets, set A with points 5, 4, 4.5, 5, 4 and set B with 4.7, 4.5, 4.4 4.5, 4.4, which
has the larger standard deviation? - (ANSWER)Set A
When you are told an experiment has an average value of 3.2 and a standard deviation of 0.25 it means
that - (ANSWER)About two out of three values in the experiment fall in the range 3.45 and 2.95
If you are told that the temperature is increasing at a rate of 0.75 degrees a second in your experiment at
a time 2 seconds into the data collection run, the best way to check the rate of change is to -
(ANSWER)find the slope of the temperature curve by selecting points around 2 seconds to see if it is
close to 0.75
In Excel, the way to enter an equation in a cell is to - (ANSWER)put a "=" sign in the cell before the
equation
The reason you have to square the differences between the values you measure and their average value
when computing a standard deviation about the mean value is that the sum of the deviations is always -
(ANSWER)zero if you don't round off so the sum cannot be used to measure the average spread in the
values

The type of Chart in Excel that we use to plot data so the first column is on the x-axis and the second
column is on the y-axis is - (ANSWER)XY Scatter
~LAB 2~ - (ANSWER)~LAB 2~
The built-in motion detector in the Go-Direct sensor cart reports the position traveled by the cart. If the
cart is pushed in the direction pointed by the arrow on the top of the cart, - (ANSWER)the measured
distance increases and the velocity it records is positive
On a level track, after the cart is given an initial push we expect the average acceleration (neglecting
friction) to be close to - (ANSWER)zero
