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
,2|Page
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
,3|Page
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
On an inclined track we expect the average acceleration of a cart
released from rest at the top of the track as it rolls down the track to be
......ANSWER......a negative constant
In constant acceleration motion when the acceleration is not zero, we
expect the position curve of a moving object to be
......ANSWER......quadratic in time
, 4|Page
In constant acceleration motion where the acceleration is not zero we
expect the velocity as a function of time to be ......ANSWER......linear in
time
When a cart rolls up a ramp, reaches it highest point, then rolls back
down we expect the slope of the position curve when it reaches the
highest point to be ......ANSWER......zero since the velocity has to go to
zero at a turning point
Suppose a cart moves at an approximately constant speed measured to
be 0.314 m/s with a standard deviation of 0.025 m/s according to
Logger Pro. The acceleration should be close to ......ANSWER......zero
after averaging
Suppose a cart moves at an approximately constant speed measured to
be 0.314 m/s with a standard deviation of 0.025 m/s according to
Logger Pro. The slope of the position curve should be close to
......ANSWER......between 0.339 m/s2 and 0.289 m/s2 with ~68%
confidence
In Logger Pro, the Statistic tool is best used to measure
......ANSWER......data that roughly constant and fluctuates around a
horizontal line in the graph
If the acceleration is measured to be a negative constant value, then we
expect the velocity curve to be ......ANSWER......a line that has a
negative slope
