◉ 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
◉ You are given the following set of data points:
xy
12
2 2.5
3 3.0
4 3.5
The slope of the data is closest to Answer: 0.5
◉ The intercept for the data set:
, xy
12
2 2.5
33
4 3.5 Answer: is 1.5
◉ 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
