When the river enters the sea or any other watercourse, where the flow of water is slow and cannot further carry the sediment brought by the river, the sediment is dropped at the river mouth and which results in the formation of a delta. It is not exactly same as an estuary, which is a coastal water body, where the river meets the sea or any other watercourse, with brackish water. In short, the basic difference between estuary and delta is that the former is a tidal mouth of the river, where … [Read more...]

Kharif crops require hot and wet climate whereas cold and dry climate is best suited for Rabi crops. Rainfall plays a significant role in … [Read more...]

While carrying out the experiment, the researcher has two objectives, relating to the validity, i.e. draw conclusions about the impact of an independent variable on the group under study and make inferences about the population as a whole. The first objective stresses on internal validity, whereas the second focuses on external validity. The basic difference between internal and external validity is that the former talks … [Read more...]

Simply, the validity of the measuring instrument represents the degree to which the scale measures what it is expected to measure. It is not same as reliability, which refers to the degree to which measurement produces consistent outcomes. For the purpose of checking the accuracy and applicability, a multi-item measurement scale needs to be evaluated, in terms of reliability, validity, and generalizability. These are certain preferred qualities which gauge the goodness in measuring the … [Read more...]

Variable refers to the quantity that changes its value, which can be measured. It is of two types, i.e. discrete or continuous variable.

Skewness, in basic terms, implies off-centre, so does in statistics, it means lack of symmetry. With the help of skewness, one can identify the shape of the distribution of data. Kurtosis, on the other hand, refers to the pointedness of a peak in the distribution curve. The main difference between skewness and kurtosis is that the former talks of the degree of symmetry, whereas the latter talks of the degree of peakedness, in the frequency distribution. Data can be distributed in many ways, … [Read more...]
