Notice here we have the variable exam score and GPA and on these two variables we have 6 people that have a value on each. So, for example, the first person has a score of 85 on exam and a GPA of 3.23. To obtain the mean and standard deviation in SPSS using the frequencies procedure we want to go ahead and select analyze on the menu bar and then descriptive statistics and then go ahead and select the first option, frequencies. We're going to move these two variables to the variables box. So, wi

While calculating the Standard Error of Measurement, should we use the Lower and Upper bounds or continue using the Reliability estimate. I am using the formula : $$\text{SEM}\% =\left(\text{SD}\times\sqrt{1-R_1} \times 1/\text{mean}\right) × 100$$ where SD is the standard deviation, $R_1$ is the intraclass correlation for a single measure (one-way ICC). http://stats.stackexchange.com/questions/9312/how-to-compute-the-standard-error-of-measurement-sem-from-a-reliability-estima spss reliability share|improve this question edited Apr 8 '11 at 1:15 chl♦ 37.5k6125243 asked Apr 7 '11 at 12:36 user4066 You seem to be calculating the coefficient of variation of the measurement, not the standard deviation or standard error. –GaBorgulya Apr 7 '11 at 14:47 @GaBorgulya Usually, SEM is computed in a different way; contrary to SD or SE, it is supposed to account for scores reliability, specific to the measurement instrument. –chl♦ Apr 8 '11 at 1:10 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote You should use the point estimate of the reliability, not the lower bound or whatsoever. I guess by lb/up you mean the 95% CI for the ICC (I don't have SPSS, so I cannot check myself)? It's unfortunate that we also talk of Cronbach's alpha as a "lower bound for reliability" since this might have confused you. It should be noted that this formula is not restricted to the use of an estimate of ICC; in fact, you can plug in any "valid" measure of reliability (most of the times, it is Cronbach's alpha that is being used). Apart from the NCME tutorial that I linked to in my comment, you might be interested in this recent article: Tighe et al. The standard error of measurement is a more appropriate measur
Is It? The standard deviation is a number that indicates the extent to which a set of numbers lie apart. Standard Deviation - Example Five applicants took an http://www.spss-tutorials.com/standard-deviation-what-is-it/ IQ test as part of a job application. Their scores on three IQ components are shown below. Now, let's take a close look at the scores on the 3 IQ components. Note that all three have a mean of 100 over our 5 applicants. However, the scores on “iq_verbal” lie closer together than the scores on “iq_math”. Furthermore, the scores on how to “iq_spatial” lie further apart than the scores on the first two components. The precise extent to which a number of scores lie apart can be expressed as a number. This number is known as the standard deviation. Standard Deviation - Results In real life, we obviously don't visually inspect raw scores in order to see how far they lie apart. Instead, mean and standard we'll simply have some software calculate them for us (more on that later). The table below shows the standard deviations and some other statistics for our IQ data. Note that the standard deviations confirm the pattern we saw in the raw data. Standard Deviation and Histogram Right, let's make things a bit more visual. The figure below shows the standard deviations and the histograms for our IQ scores. Note that each bar represents the score of 1 applicant on 1 IQ component. Once again, we see that the standard deviations indicate the extent to which the scores lie apart. Standard Deviation - More Histograms When we visualize data on just a handful of observations as in the previous figure, we easily see a clear picture. For a more realistic example, we'll present histograms for 1,000 observations below. Importantly, these histograms have identical scales; for each histogram, one centimeter on the x-axis corresponds to some 40 ‘IQ component points’. Note how the histograms allow for rough estimates of standard deviations. ‘Wider’ histograms indicate larger standard deviations; the scores (x-axis) lie further ap
