Question

Thursday BIOL118: Choosing appropriate analysis given data. Name: rala Palmore 1. Evaluate whether there is a significant relationship between wing length (mm) and tail width (mm) for this species of bird. 1st wing length pairs with 1st tail width, and so forth. Wing length: 102, 102, 103, 104, 106, 107, 108, 108, 111, 112, 114, 115 tail width: 71,72,74,74,78,74,72,76,78,79,77,83 Name type statistical analysis, explain why it is the correct analysis, and give total df's 2. The following data measure the number of days it takes potato leafhoppers to develop from egg to adult at each of 4 temperatures. Each data point represents an independent sample. Is there a relationship between temperature and time to adulthood? 190 C 21°C 23 0C 250C 58.2 56.3 50.1 52.9 57.2 54.5 54.2 49.9 58.4 57 55.452 55.8 55.3 52.1 51.7 54.9 53.2 56.8 55.0 Name type statistical analysis that should be used and explain why that analysis is correct. Give the total degrees of freedom.

Explanation / Answer

Questiion 1

Type of statistical analysis is "Regression Analuysis"

Here it is correct analysis as we will find the correlation between Wing length and tail width through regression analysis and if found significant we can establish a relationship.

Here dF = (n-2) = 12 -2 = 10

Question 2

Here we will perform One way anova anslysis.

Total degrees of freedom = (n-1) = 4 * 5 - 1= 19
