RESPONSE #1

A standard deviation is calculated by squaring all the deviations from a sample of a data set, then summing those answers. Then divide that total by one less than the sample size. This will give the average squared deviation. Finally you take the square root of that number to get the standard deviation.

RESPONSE #2

When there are data points you take an imagined line and place it so that the average distance from each data point is as minimal as possible. If the data point are relativelty close then the line will not have much room for error, however if the data points are scattered then the best fit line has much greater room for error or a difference of opinion at least, varying what some people may calculate as the slope and the y-intercept.

RESPONSE #3

Velocity is simply how fast an object is traveling usually in some units vs time. In your car your velocity changes from takeoff to riding on the interstate. In the beginning the velocity will increase until reaching the interstate where the velocity will approach a ""constant"" rate of speed.

RESPONSE #4

Multiply the average speed by the given time interval. Example: 60m/h*1 hour=60 miles. The unit of time cancels out in the multiplying.

RESPONSE #5

Divide the average speed by the given distance traveled.

RESPONSE #6

Distance traveled divided by time interval gives average speed. Example 60 miles in 1 hour =(60 miles/1 hour)= 60 mph

I can't tell from this document what the questions are, though your answers are well-expressed and likely correct.

I need all the information, in order, on one page.

That is the purpose of the q_a_ and query programs, and the forms used for the labs.

It appears that you have run the query for these assignments. If so, then there will be a SEND file in your c:\vhmthphy folder.

In that case, open the file, copy the contents into the Submit Work Form, and submit it.

If not, please go back to Orientation Steps 3 and 4 so you will understand the SEND file. You should actually do this in any case. It should take you well under an hour, and will save you more than that in the long run.
