Explain Non Probability sampling methods. Give one example of each. Non-probability sampling Non-probability sampling is that sampling procedure which does not afford any basis for estimating the probability that each item in the population has of being included in the sample. In this type of sampling‚ items for the sample are selected deliberately by the researcher; his choice concerning the items remains supreme.

Tab 1----All graphs‚ including the histogram should have an appropriate title and the x and y axis should be labeled. Bin and frequency does not give any information as to what is being represented by the numerical data in the histogram (hint: Electricity cost (in $) and one-bedroom apartments). As Professor Ellis stated in the lectures‚ graphs should be able to stand alone. “A Graph should sing its song!” Bin ranges are correct. However‚ the largest percentage does not lie between 139‚ 179.
