What else can I help you with?
What statistical test do you use for nominal by ordinal data?
Kruskal-Wallis H test.
What is the power of a statistical test?
The power of a statistical test is the probability that the test will reject the null hypothesis when it is, in fact, false. Please see the link.
Can one research test more than one hypothesis?
Yes, if the data collected will relate to more than one of them.
Is there a statistical test to assess the difference between two ratios. I have numbers which are ratios and want to test whether there is a statistical difference between them?
You can use the z test for two proportions. The link below will do this test for you.
How is the power of a statistical test defined?
The power of a statistical test is defined as being a probability that a test will product a result that is significantly different. It can be defined as equaling the probability of rejecting the null hypothesis.
What type of data would need to be collected to conduct a t test?
What type of data would need to be collected to conduct a test and why?
What statistical tests can I use on data collected from quota samples?
The simple answer is you cannot use statistical tests on data collected from quota samples. Unless the sample was collected using a random sampling technique you cannot have any confidence in the results being representative of the population you are sampling. Quota samples are non random. However this does not stop researchers from using statistical tests on quota samples, even if the results can be taken with a pinch of salt!
What statistical test do you use for nominal by ordinal data?
Kruskal-Wallis H test.
When do you use goodness of fit in statistical analysis?
statistical goodness of fit test used for categorical data to test if a sample of data came from a population with a specific distribution. It can be applied for discrete distributions.
Why is the examination of collected data important?
Examination of collected data is important because, if you examine it you could check if something's wrong or another test or collection and compare the data you have to the test or collection you just did.
What kind of test to analyze data from experimental treatments?
Analyze data from experimental treatments using statistical tests such as t-tests, ANOVA, or regression analysis for comparing means between groups or examining relationships between variables. Choose the appropriate test based on the research question, experimental design, and nature of the data collected.
How are experiments used to test claims?
..Data are collected and compared with the claim.
What term refers to information gathered to test a hypothesis?
The term is "data." Data is collected and analyzed to test a hypothesis and draw conclusions in scientific research and experiments.
What is the measured or the tested by the data collected in an experiment?
The data collected in an experiment test a hypothesis. A hypothesis is an educated guess about a specific question, usually regarding science.
What are examples of parametric and nonparametric statistical tests?
Parametric statistical tests assume that your data are normally distributed (follow a classic bell-shaped curve). An example of a parametric statistical test is the Student's t-test.Non-parametric tests make no such assumption. An example of a non-parametric statistical test is the Sign Test.
How does a method test a hypothesis?
A hypothesis test is used to make certain decisions based on the data collected.
What would your experimental approach be to test this hypothesis?
To test the hypothesis, I would design a controlled experiment where I manipulate the independent variable while keeping other factors constant. I would randomly assign subjects to either a treatment group or a control group to minimize bias. Data would be collected pre- and post-intervention, and statistical analysis would be used to determine if there are significant differences between the groups. This approach would help establish a causal relationship and validate or refute the hypothesis.
