group comparison

Hello I want to make a comparison between the groups. However, in the control group, all of the data was set to be 100% and the data of the other groups is the proportion compared to the control group. So the data will look like, (just for example) control group: 100%, 100%, 100%, 100%, 100%...

Hi, I did experiment to compare the effect

Hi all, I have asked respondents in a survey to rate 10 different communication channels (e.g. email, phone, face-to-face...) from 'Not important' (1) to 'Very important' (5). Can I now split these 10 channels into two categories (e.g. offline, online), in order to see whether there is a...

I am working on my independent action research project and need help figuring out what statistical test to use. I am looking at how my students' waste management knowledge and behaviors change pre- and post- survey. Usually, when I have done something like this, I run a paired t-test since...

Hi I have two categorical variables as in below example: Region Dim Value PK Dim1 2 PK Dim2 3 PK Dim3 -1 PK Dim4 -4 US Dim1 -0.5 US Dim2 4.3 US Dim3 2.1 US Dim4 2 PK Dim1 5 PK Dim2 -0.4 PK Dim3 -0.3 PK Dim4 0.8 US Dim1 1 US Dim2 2 US Dim3 0.8 US Dim4 1 I want to compare the variables US and PK...

Hi there, I have pre/post data on the same tool for two different populations (Group A: Higher needs, Group B: Lower needs) and two different services (Intensive counseling for group A, Brief counseling for group B). Other variables include age, gender and length of service. Would it be...

Hello. I am new to this forum but it looks like it will be a great reference! For my thesis I used Mantel tests to compare non-parametric behavioral data against genetic relatedness data. So, I had behavior rates in a square matrix and compared them against genetic relatedness values in a...

Hello, I carried out a screen for 400 different genes. This was done in batches of 20 genes. Each batch includes 2 replicas of an internal control: a gene that works as a negative control. There is batch to batch variation and the differences between the batch means for the parameter being...

Hello, During my study of animal behavior, each of my 10 study subjects (all young females) received a number of aggressions from individuals belonging to 4 different age/sex groups (namely, immature males, mature males, immature females, and mature females). My prediction was that young...

This is tangentially R-related, but mostly about presenting results of a regression including interaction terms. My ultimate objective is to produce a coefficient plot representing differential associations between a set of predictors and responses for two groups. To this point, as an...

I have a data set of N subjects, and P variables, with some vars measuring performance on a task, and some measuring subjects' intrinsic characteristic. Each of the performance variables consists of the proportion of correct responses (range 0 to 1.0) to some set of questions. The characteristic...

I have performed an experiment wherein the same people got to rate product 1 and product 2 on several items. These items together form latent constructs. I am modeling a simple model where I estimate the paths between 1 independent latent variable, a mediator (latent) and a dependent (observed)...
