Is a standard deviation of 18 considered high?
The standard deviation, in itself, cannot be high nor low. If the same measurements were recorded using a unit that was a ten times as large (centimetres instead of millimetres), the standard deviation for exactly the same data set would be 1.8. And if they were recorded in metres the sd would be 0.018
In statistics what shows how far away a measurement is from the mean or average of the set?
The "z-score" is derived by subtracting the population mean from the measurement and dividing by the population standard deviation. It measures how many standard deviations the measurement is above or below the mean. If the population mean and standard deviation are unknown the "t-distribution" can be used instead using the sample mean and sample deviation.
How do you calculate standard deviation without a normal distribution?
You calculate standard deviation the same way as always. You find the mean, and then you sum the squares of the deviations of the samples from the means, divide by N-1, and then take the square root. This has nothing to do with whether you have a normal distribution or not. This is how you calculate sample standard deviation, where the mean is determined along with the standard deviation, and the N-1 factor represents the loss of a degree of freedom in doing so. If you knew the mean a priori, you could calculate standard deviation of the sample, and only use N, instead of N-1.
How do you construct a trapezium?
first of all i will need a compass,scale,protector,pencil,eraser,pen if you dont use you can use pencil instead of it.THEN
How do you Calibrate a timex digital compass?
Go to the Timex web site and look up "manuals". They have enough of a listing to figure out the correct procedure for your device. Here is the URL for the page I'm speaking of. http://assets.timex.com/manuals/?timexBrand=core I own the Expedition Adventure Tech Digital Compass Watch, and the following instructions will calibrate its compass. A. To calibrate for magnetic north, press and hold HEADING (from TIME OF DAY mode only) until ROTATE WATCH TWICE appears in the display. B. Hold watch level relative to the horizon (on your wrist, in your palm, or on a non-metallic table). Rotate watch slowly two complete rotations (taking at least fifteen seconds per rotation). Press MODE when finished. (Two-step calibration: Upon completion of STEP A, press HEADING. Do not enter a value for declination angle. While in TIME OF DAY mode, press HEADING. A heading will be displayed. Noting heading value, adjust watch position for heading of 150 degrees. Initiate calibration by pressing and holding HEADING until ROTATE WATCH Twice is displayed. Repeat calibration procedure as discussed in Step A. At completion of calibration proceed normally to Step C.) C. Watch will then call for you to enter DECLINATION. Pressing HEADING will exit calibration mode and leave watch set to measure magnetic north. Entering a declination value instead will allow the watch to point to true north, by adjusting for the angle, which varies for different spots on the globe. D. To set watch for true north, enter declination angle for your location from the chart below. Press START to advance flashing TENS OF DEGREES, press MODE to select DEGREES, then START to advance. Press MODE to select direction, then START to switch between E and W. Press HEADING to exit calibration and save new values. TABLE 1.

How do you know the plane heading using Airbus in Flight simulator?
Typically the compass rose. Some systems use a heading tape instead.
When do you use the relative standard deviation instead of standard deviation?
Use %RSD when comparing the deviation for popolations with different means. Use SD to compare data with the same mean.
What metal does a compass have to be away from to work?
Iron or steel. Since it is a magnet, a compass will point to iron instead of pointing North.
What is the purpose of quartile deviation?
In a data sample, the purpose of quartile deviation is a way to measure data dispersion instead of using the range. The quartile deviation is found by subtracting the lower quartile from the upper quartile, and dividing this result by two.
What are days off called when they are used to compensate instead of being paid money?
I believe this is called "comp time" (compensated time)
Why you use mercury lamp instead of ordinary light or sodium lamp in constant deviation?
we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
What is effect of using a gps instead of a compass?
A compass - can only indicate a direction to travel. A GPS receiver - can not only show you which direction to go, but how far away you are from your destination.
What are Deviation-Based Outlier Detection?
Deviation-based outlier detection does not use the statistical test or distance-based measures to identify exceptional objects. Instead, it identifies outliers by examining the main characteristics of objects in a group.
What is a positive effects of using a GPS instead of a compass?
A compass - can only indicate a direction to travel. A GPS receiver - can not only show you which direction to go, but how far away you are from your destination.
Will a compass always work?
No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

Is standard deviation the arithmetic mean of the squared deviations from the means?
No. Standard deviation is the square root of the mean of the squared deviations from the mean. Also, if the mean of the data is determined by the same process as the deviation from the mean, then you loose one degree of freedom, and the divisor in the calculation should be N-1, instead of just N.
What is an oblique heading?
An oblique heading refers to writing headings using oblique text. These texts are similar to italics, but they lean right and they are only distorted versions of the typefaces instead of separate glyphs.
