Unformatted text preview: 5. The VI tscore_err.vi computes the Student’s t—score for two sets of sampled data. The t—score of trip sets of data indicates whether there is signiﬁcant difference between the means of the two sets. These two sets of data can be dependent or independent of each other. The steps to compute the t—score are the following: a. Compute the means of the two data sets, calling them 2,, and it, (we have used the i symbol to indicate that we are taking the mean of a sample, which says that the data at hand are part of a larger data which is the most practical case]. b. Compute the sum of the squares of the error for the two sets of data, calling them SSEa and SSEh. c. Determine the sample variance using the formula 2 = SSEa + SSEh (na - 1) + {nb - 1) where n is the number of samples for each data set. d. Determine the standard deviation of the sampling distribution of the samplemean differences using 5 the formula 52 52 cr = — + — 1'13 nb e. The t—score is then computed as liar _ ibl t: 5 Using LabVlEW’s debugging tools, troubleshoot the VI which should give the correct t-score for the following set of fifteen data: Data set A: 26, 26,26, 21,18,21,19,25, 23, 29, 22, 22,24, 23, 22 Data set E: 18, 20, 2D, 26, 17, 23, 20,16, 21, 18, 21, 29, 20, 25, 19 mmmwwiuﬁmmudp =>§>DII Vﬁhula‘u: wwmh h>— Slandald Dariaﬁun Sample Variam a 1 m as an v...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
