1. Role a sample plays in making statistical inferences about the population

The sample plays an essential role in the process of making statistical inferences about the population. Ordinarily, the entire population is usually too large to be fully studied. The limitations that limit study of an entire population include costs, time and convenience in the application of the study modes. A sample from the entire population is selected. It is assumed that the sample would be representative of the entire population and contains minimum bias towards any aspect of the population. The sample, therefore, forms the basis on which the population characteristics are inferred. The researchers assume that the characteristics ...

1. Box-and-whiskers Plot Box-and-whiskers plot is a graphical representation of data that shows the values of quartiles (i.e. quartile 1, 2 and 3) within a rectangular box. In this graph, the ends of the box represent quartile 1 (Q1) and quartile 3 (Q3), while quartile 2 (Q2) represents the median-the horizontal line inside the box. The length of the box-the difference between Q1 and Q3-is known as the interquartile range (i.e. IQR = Q3-Q1). Whiskers are lines inside the box drawn at the median. These lines represent extreme values within the observable range. It is also the line which corresponds to a ...
