-if the SD is 6 and n=64 then what is the SEM
- 0.75. The SEM = SD / √ n
-What does a Mann-Whitney U statistic depend upon
?
The MannWhitney U statistic depends upon ranking the data
-Rank the following data: 0.15, 0.33, 0.05, 0.8 and 0.2
.
And 0.8
-Is the X^2 test a parametric test
X^2 ?
No, the χ2 test is a non-parametric test
, χ2
-What is the application of non-parametrical tests
?
Non-parametric tests are used when no assumptions can be made about the population distribution of the data.
,
-What is the convolution integral
?
The convolution integral gives the output of a system in terms of the input and the characteristic response of the system to a unit impulse
-What do you get if you multiply the Fourier transform of a signal by the frequency response of a system
, ?
If you multiply the FT of a signal by the frequency response of a system then you get the FT of the
Output from the system.
