# chi-square goodness of fit test

1. ### Help on Chi-Square Statistics

Hi, I have an experiment for my masters thesis and I’m confused about which statistical test I should use. In my experiment I’m looking if there is an association between food types and locations. My variables are food type (with 4 levels) and location (with 8 levels). The experiment has 3...
2. ### Help on Chi-Square tests and G*power sample size estimation!

Hi, I'm having trouble figuring out which statistical test I need to use for my experiment. I want to see if certain types of food items are represented in certain locations. To test this I have an experiment where participants place items into locations as they desire. After that, they learn...
3. ### How do I test if my data is Poisson Distributed?

I'm unsure as to what the correct way is to calculate Pearson's Chi-Squared statistic from my data to then test if it is Poisson distributed. (I'm working in RStudio) Here is my data: > X [1] 70 60 60 57 100 100 75 60 65 70 120 60 65 60 80 90 65 80 75 75 100 65 90 60 150...
4. ### Can I increase the sample size by generating random numbers to apply the Chi-Square Goodness of Fit Test?

Does increasing the sample size by random number generation change the distribution? I have a sample of size 8. Each sample value represents the number of bus arrivals at a bus stop every 15 minutes. But I wanted to apply the chi-square test to verify the fitting with the Poisson distribution...
