05 One-Sample t-Tests in SPSS - SPSS for Beginners

When we calculate the mean of a sample, we can then use a one-sample t test to compare that sample mean to another mean, such as a mean from a population, a normative group, or another known value (mean). The “one sample” t test is also called a “single sample” t test. You are comparing the mean from a sample to a single mean. This video will introduce you to concepts that you will need later when you learn about hypothesis testing.

sir what is the difference between standard deviation and z score ? and could u give an example, please?
@rishikamalik4752 6 жыл бұрын
standard deviation is a measure of dispersion- it tells you by how much individual values are different from the mean. another word for stan dev. is volatility. Z score is simply a way to standardize individual values in a sample. think of a z score as a scaled, or standardized version of a value. the formula to arrive at a z score is: (Value- Mean)/Stan deviation

I shall indeed tell my students. I'm a scientist (I am an Ed.D in Nutrition Education and I really. stumble with statistics). I "get" the whole picture of stats, but analyzing my own data gives me a sense of terror. I think it's conditioning as a young girl who was always at the top of my class who fell behind (when I was a teenager, with boys screaming out answers in class) in math. I know math is NOT statistics, but still, it's numeracy knowledge, which I feel I lack!

I’m confused, you used the 2.262 critical value from the two-tailed column instead of the one-tailed one. You are explaining for the one sample t-test (one tailed t-test) I figured that anyway, in the end the result is not significant due to the confidence interval not being 0 nor having our t value exceed the one tailed critical value of 1.8. The significance value also surpasses the alpha level. Could you(or anyone) point this out to confirm my confusion and offer some clarity? Thanks! The videos you provide are good! I appreciate it!
@ResearchByDesign 6 жыл бұрын
The test is a one SAMPLE test (comparing a single sample to a known population value), but we are using a two-TAIL variety of the test because we want to know if the sample mean is "different" than the known value. We would use a one-TAIL, one SAMPLE t test if we compare a single sample and ask if the sample mean is "higher" than the population value. So the one sample refers to our research design and the one/two tail refers to our research question. Hope that helps.

@ResearchByDesign 3 жыл бұрын
That comparison value should be chosen as either the mean of the population from which the sample was chosen, or sometimes the mean of a test (such as comparing to an average IQ of 100). It should be a meaningful, comparable value. If you don't have one of those, then your test will not be meaningful.

@ResearchByDesign 3 жыл бұрын
You would use the 2-tail test when your hypothesis is that the groups differ, but you do not state whether the mean will be higher or lower. Also, there is no specific option to interpret a 1-tail test in SPSS. You have to use the 2-tail output and then interpret what the cutoff score would be for a one-tail test. Hope that helps.

Well, I wanted to show this to my students except you have a flaw in here - you talk about comparing people in the U.S. to people from another country. That would be an indep. t-test because the sample from the other country is not a subset of the American population. A single sample t-test would be comparing a sample (and its mean) to the population parameters (e.g., the population mean) that the sample is selected from.
@ResearchByDesign 4 жыл бұрын
That depends on two things: your research design and how you want to define your population. I was thinking of humanity being the population and using a mean established by a researcher from a study in another country (perhaps with a given diagnosis, job description, or other signifier) to see if similar people in America scored the same. You could compare an American sample to an established mean (or other known value) using the one-sample t test. You would need to have the sample data from both countries to do an independent t test, but you certainly could design a study in that way. Best to you and your students. Thanks for commenting.

@ResearchByDesign 4 жыл бұрын
Hey, you sound a little overwhelmed with stats. Let's keep it simple. First, stats is all about numbers. Sometimes we count things, or measure them, or just use numbers to label groups (Group1, Group 2, etc.). So when you count things, you use frequency. How many of each do you have? ANOVA and t tests are for when you measure something and you want to see if the measurement is different between 2 groups (indep. t test) or 3+ groups (ANOVA). You can also do repeated measures where you measure the same group twice (paired or RM t test) or 3+ times (RM ANOVA). Correlation is when you measure two things (temperature & sales) then you look for a relationship between them (do sales go up when it gets colder?). I have playlists for all of these, so please check those out and see if that helps walk you through your course. Wish you the best. You're going to get through this!

Hello Sir, I really need your help 1. I have four groups in my experiment (one control and three experimental), I feed to control group the normal diet and to experimental groups normal diet plus different percentage of same supplement. Now I don't know how to calculate p-value of different groups (if adding supplement significantly affect the three experimental groups compare to control group or not). I have mean of live body weight of them from 12 days along the experiment (from begging till the end of the trial). 2. I have different mortality rates (%) in control and experimental groups, how to find if the mortality rate in experimental groups is significant or not compare to control group? thanks in advance Mohammad from Kabul Afghanistan
@ResearchByDesign 2 жыл бұрын
You should use a one-way ANOVA with four levels. Assuming that your samples/groups are each the same size, use a Tukey post hoc test if the F test is significant. It will help you see which groups differ. You can use weight as the DV. For % mortality, you can use a proportions test with a Bonferoni correction (set p = .0125 for 4 groups as your criteria for significance between groups). Hope that helps
@ResearchByDesign 2 жыл бұрын
One more thing...if all you want to do is compare each group to control, you ca use planned contrasts to control the p value error rate, instead. For the DV, I'd suggest using the beginning and ending weights, but that would change your design to a mixed ANOVA (instead of one-way). Wonderful to talk to someone from Kabul...wish you the very best for you and your country.
