MHB Need assistance to decide with analysis to use for problem

Click For Summary
The discussion focuses on analyzing how construction stilts influence walking patterns based on user experience. The researcher has two groups: expert and novice stilt users, and plans to compare their walking parameters both with and without stilts. An independent t-test was initially considered for analysis, but it was pointed out that there are actually four samples due to the two parameters of expertise and walking condition. Therefore, a more suitable statistical method, ANOVA, is recommended for this analysis. Using ANOVA will allow for a comprehensive comparison across all groups and conditions.

I am interested in examining how construction stilts affect walking patterns, and how experience with the stilts affects walking patterns. I recruited a group of expert construction stilt users, and a group of novice users and videoed their both walking on stilts and without stilts. I want to see if there is a difference in walking parameters between groups and between the walking conditions.

I am considering using an independent t-test for two samples. Is this the correct approach?

Thanks,

Dants

Hi Dants, welcome to MHB!

A 2-sample t-test is to test if the means of 2 samples are different.
However, it appears you have 2 x 2 = 4 samples.
That is because you have 2 parameters: construction and expertise.
In such a case we need a more general method that can be applied to more than 2 samples: ANOVA.
 

Thread 'A variant of the Monty Hall problem'

There is a nice little variation of the problem. The host says, after you have chosen the door, that you can change your guess, but to sweeten the deal, he says you can choose the two other doors, if you wish. This proposition is a no brainer, however before you are quick enough to accept it, the host opens one of the two doors and it is empty. In this version you really want to change your pick, but at the same time ask yourself is the host impartial and does that change anything. The host...
