Hello I am having airborne dust concentrations data for >1 micron size, >3 micron, 5 micron and >10 micron size. (> means greater than) These data was taken before and during dust producing work in field study. N=5 How can i compare these before and during operations data ? It seems that there is relative percent variation in dust concentrations in atmosphere between before and during operation data. (Taking >1) micron as 100 %) Before operation: The relative percent variation of concentration with different particle size is as below. For example Concentration of >1 micron size particle is 100%. >3 micron: 80% >5 micron : 60% >10 micron: 40%. During operation: Concentration of >1 micron size particle is 100%. >3 micron: 90% >5 micron : 80% >10 micron: 70%. It seems that >10 micron particle share is increased due to that machine operation...? Which test is suitable for analysing these type similar data for discussion ? How to use statistics? Any comparison among these concentrations of different particle sizes ? thank u.
