Identify experimental and treatment design A Dependent Varia

Identify experimental and treatment design.

A. Dependent Variable: Growth of grass on golf course in 24 hours (mm)
Treatments: Want to compare 4 fertilizers, and 4 weeks. All 16 combinations will be used.
Experimental Material: We have 18 greens at a golf course. On each green we can mark off 4 small
plots, and each can be given a fertilizer level. Growth is measured on each plot for the next 4 weeks,
giving a maximum of 18 greens * 4 plots * 4 weeks = 288 observations.
Concerns: Greens are likely to differ due to shade, irrigation, etc.

Solution

Experimental - Growth of grass variable in 24 hours on golf course.

Treatment design - 4 fertilizers with other variables as shade , irrigation,etc
