Rheumatoid factors (RF) are a group of proteins present in the blood of the patient, suffering from rheumatoid arthritis. It is believed that rheumatoid [...]
After reading this article you will learn about the chi-square test and its interpretation. In genetic experiments, certain numerical values are expected based on segregation ratios involved. However, in actual field experiments exact values may not be obtained due to in-viability of certain pollen grains, zygotes, no germination of some seeds, or even death of few plants after germination. This [...]
This article provides notes on Duncan's multiple range test. For experiments, requiring the comparison of all possible pairs of treatment means, the LSD test is usually not suitable, when the total number of treatment is large. In such cases, DMRT is useful. DMRT involves the computation of numerical boundaries, that allow for the classification of the difference between any 2 [...]
