sample statistic
Mean or average is the most common measure of central tendency of a sample.
sample rate difference. they have to be set to the same sample rate
A sampling rate is a term that is used in digital recording to describe how much, and how often, data is used. In digital audio (sound recording), a new sample of analog data -- a new speaker position -- is sent out to the speaker quite often, usually at a sample rate of 44100 Samples/second. So when the music is recorded for a CD, a new sample is collected from the microphones just as often, usually at a sample rate of 44,100 Samples/second. A biologist may measure the temperature of a lake once a week. That temperature data has a sampling rate is 1 Sample/week. Sampling rate is independent of "channels" or "bit resolution". A highly instrumented concert may have a dozen channels, each one from a microphone sampled at 44100 Samples/second, but the total sampling rate is still 44,100 Samples/second.
A USB soundcard may tax your processor and can introduce some latency.

Yes -- your soundcard can be used to record from virtually any source.
Go to the soundcard manufacturers web site to download a copy of the drivers. Alternatively, if the soundcard is integral to the motherboard, use the motherboard installation disk to find the soundcard drivers.
-- Get a piece of the material. It doesn't matter what size it is. -- Measure the mass of the sample. -- Measure the volume of the sample. -- Divide the mass by the volume. The result is the density of the material.
TV audio can be routed to a soundcard either via analog RCA, digital COAX, or SPDIF, depending on what is available on your specific TV and soundcard models.
Statistically speaking, the mean is the most stable from sample to sample. Whereas, the mode is the least stable statistically speaking from sample to sample.
