Ok, I hope someone might be able to offer me some assistance into why i'm seeing a difference between what i believe to be the correct method to calculate dependant probability. Scenario: Coin bag of 8 weighted coins containing coins weighted for heads (0.5, 0.5, 0.6, 0.6, 0.7, 0.9, 0.5, 0.5)...

Hi everyone, I am examining the differences in media coverage of homicide on the basis of the religion of the victim (bias). The sample is one newspaper over several years. The quasi-independent variable is religion (1 = christian, 2 = muslim).. This is not a dichotomous variable as...

Can someone tell me the statistical tests I could use with the following variables. Independent variable categorical (high, medium, low) Dependent variables are categorical, and some are dichotomous What parametric (for large samples) and what non-parametric (small samples) could be...

I asked the following question in an exam. I can argue both ways, but I am very interested in any further thoughts. ---------------- Are the following events independent or dependent? Please give details of your choice. No marks will be given for answers without a reason. Event A –...

Hello! In short: I'm having issues with figuring out a technique to measure how well does a categorical variable explain variation among a nominal variable, resulting in a simple numeric expression. More precisely. The dataset that I'm using contains individual level data on the...

I am conducting a psychology experiment. In my pilot study I analyze responses of one subject which ran through two conditions. The task is to predict outcomes based on previous outcomes. On every trial the subject tries to predict the outcome as good as possible and learns to adapt the...

Does a Weighted Paired T-test exist? I am comparing the percent of a population that are juvenile between 'Autumn' and 'Spring' at many sites. The Sample size (n) is variable among the sites and between the seasons. Sample data: Site___Fall %__n_____Spring %__n...

Variables A variable is an object, event, quantity, time period or basically something you are trying to measure. We can then further discriminate between two types of variables: independent and dependent. Independent variables An independent variable is exactly what it sounds like, it isn't...

Hi everyone, I am new to this forum, and still figuring out how to navigate the site. So, I apologize if this question has already been asked. In short, I am attempting to compare two dependent effect sizes. To be more detailed, I have two sets of repeated measures. At Time 1, all...

Hi i am trying to construct a regression with inflation as my dependent variable and gdp and income as my independent, but i am not sure if it can be done as inflation is a percentage where as income and gdp are in terms of current $. does that factor make a difference in my ols...

Hi I am currently trying to transform 4 indicators from the world value survey to build one dependent variable to run regressions against. I am wondering if I am doing this correct, since I am a statistics beginner in SPSS? 1. Step one is that I have transformed old data and variables...

Hello, Which to use to test whether Monday sales and sales on the other days of the week are independent from each other. Case: A promotion offered on Mondays this year, so I want to "test" if the customers are trading off. The idea is to check the relation of weekdays last year and this...

I'm trying to figure out whether or not citation flow and trust flow are independent of each other (here is the article containing the data: http://www.3ders.org/articles/20120514-which-company-in-3d-printing-world-has-better-link-profile-quality.html). Is there a certain test or method that can...

Hi fellow nerds :) My dependent variable had to be transformed by square root (so the residual plot would be normal). I usually use log10 transformations and then the B value (slope) translates into the percents of the dependent variable, but what do I read from a B=-,499 (P=0,015) of a...

I have the probability distribution Functions(PDF) of the wind speeds of two wind sites which have a certain Pearson's correlation coefficient. How can I combine the PDFs of these two sites? I don't have the time stamped data of these two sites, rather, I only have the distributions and...

Hi Buddies :wave: Thanks for your upcoming help :) I have been trying to create relationship dependent scale which are (Positive, Neutral, Negative) = ( 1/ 0 / -1) and independent variable of 1 - 5. I would like to know how to evaluate impact of Independent variable on dependent variable...

Hey guys. I'm doing my masters and I'm trying to get the hang of statistics in social sciences. I have this one data set, where I'm looking at the relationship between different types of jobs and after-education in the different job types (yes/no). It's then I get a little confused. As far...
