For any researcher, the first initiative to carry out and experiment is to select an appropriate experimental design.

Previously, basic principles and terminology of experiments have been discussed. There are several methods of experimental designs according to which the researchers follow and carry out statistical analysis. Among them, Completely randomized design (CRD), Randomised block design (RBD), and Latin square design is discussed here. Completely randomized design (CRD) In …

For any scientific studies, designing and evolving suitable methodology of an experiment in an institution or for an inquiry in the field, need very logical and systematic planning. The knowledge of how experiments come in use and in what way it is to be carried out is discussed below.   …

The cell wall is structurally and chemically different from the protoplasm. The growth in thickness of walls is evident in both primary and secondary walls. The initiation of the cell wall and how it grows is being studied here. Origin of the Cell wall The wall formation is first evident …

A layer of structural materials composed of polysaccharides, glycoproteins, and phenolic compounds found external to protoplasm is called the cell wall. Certainly, it defines the shape and size of the cell. In this paragraph, the structure and composition of cell walls will be discussed explicitly. Gross Structure of Cell Wall The …

In the experiment, we measure the two continuous characters which are associated with each other. For example, the height of the plant and the temperature of the atmosphere. Accordingly, to understand the relationship between two such variables, we need to know how they are related and how the relationship can …

We can test the significance of the two sample means by using a t-test. However, in cases where there are more than two samples, it is done by Analysis of Variance (ANOVA). This method is carried out by comparing sample variances using Variance Ratio Test or F test. So at …
