Question

examples of numeric variables​

Answer 1

Numerical Variables

A numerical or continuous variable (attribute) is one that may take on any value within a finite or infinite interval (e.g., height, weight, temperature, blood glucose, ...). There are two types of numerical variables, interval and ratio. An interval variable has values whose differences are interpretable, but it does not have a true zero. A good example is temperature in Centigrade degrees. Data on an interval scale can be added and subtracted but cannot be meaningfully multiplied or divided. For example, we cannot say that one day is twice as hot as another day. In contrast, a ratio variable has values with a true zero and can be added, subtracted, multiplied or divided (e.g., weight).

Answer 2

Answer:

simulation

Explanation:

In order to verify the model that was chosen to represent the experiment, a simulation was designed to test the ability of the method to determine the location angles of 2 simultaneous sources of differing frequency. The simulation was run for both the single AVS case as well as the case of a 2 AVS array. For each scenario, three trials were run testing the effect of SNR on the ability to discern the sources apart from one another. The results of these simulations are shown in the figure below.

As the image shows, the ability to separate the sources is improved greatly with an increase in SNR for both the single AVS and pair of AVS cases. The case of 2 AVS shows an obvious advantage in the 2 source problem in that the -3dB SNR already shows a solid difference between the sources where as the single sensor case shows no definition between sources at the same level. The graphic shows that as the SNR is increased, the sources become more distinguishable from one another.
