How do you draw a bell curve?
A bell curve reaches its highest point in the middle and is lower on the sides. It can represent standard deviations from the mean.
What is the mean and standard deviations and the standard normal distribution?
Mean is the average, sum total divided by total number of data entries. Standard deviation is the square root of the sum total of the data values divided by the total number of data values. The standard normal distribution is a distribution that closely resembles a bell curve.
A What is empirical rule?
For data sets having a normal, bell-shaped distribution, the following properties apply: About 68% of all values fall within 1 standard deviation of the mean About 95% of all values fall within 2 standard deviation of the mean About 99.7% of all values fall within 3 standard deviation of the mean.
What does digitizing mean?
digital waves are recorded
Is the standard deviation the same as the mean of absolute distances from the mean?
no the standard deviation is not equal to mean of absolute distance from the mean

How much data is within 1.28 standard deviations of mean on bell shaped curve?

How do you generate a Gaussian bell shape graph when you have a mean and standard deviation and absolutely no other data?
The Gaussian "Bell" Curve has probability density function: f(x)= exp{-((x-mu)2/(2*sigma2)) } / (sigma*sqrt(2*pi)) where mu=mean & sigma=standard deviation
What does SDI mean when talking about interfaces?
SDI is an abbrevation of Standard Digital Interface. It's most known use is as interface for digital video. It's currently used a lot for the high definition video.
What is the mean and standard deviations and the standard normal distribution?
Mean is the average, sum total divided by total number of data entries. Standard deviation is the square root of the sum total of the data values divided by the total number of data values. The standard normal distribution is a distribution that closely resembles a bell curve.
What percent of a normal population is within 2 standard deviations of the mean?
By the definition of standard deviation, 95.46% of the normal population will be within 2 SD of the mean. Explanation: The normal distribution of a population means it follows the "bell curve". The center of this bell curve is the population's mean value. One standard deviation defines two areas (on the left and right side of the central "mean" value) under the bell curve that each have 34.13% of the population. The next standard deviation adds two additional areas under the curve, each having 13.6% of the population. Adding the areas under the curves on both sides gives us (34.13% + 13.6%) x 2 = 95.46%

How is digital TV different from before?
If you mean the differences between "standard" cable and digital there a few differences. Besides offering a more secure transmission and a clearer overall picture. Standard cable and digital video may both offer video-on-demand services. Standard cable often requires the use of a telephone signal, while digital cable will use a remote control or cable box. Standard cable services also can include telephone and high-speed internet options. While digital cable offers these services and interactive TV services, like, on-screen program guides, parental control, games, special programming and DVR recording.
