Population is: All the individuals, objects or scores the researcher or investigator is interested in studying In an experiment, the population is the larger group of individuals from which the participants in the experiment are taken For instance, if I am interested to find out the number of people who do not pay tax in Singapore then …
Sample is: A subset of the population. As discussed in the previous post, sample is used for:– Practical considerations– Time considerations There are generally two types of sampling: Probability sampling – random – Robust as random sampling allows selection of representative samples Non-probability sampling – non random – Less robust but might be the most appropriate for some of the studies where random sampling …
Random Sampling is: a random selection of every individual, object or score. — This implies that every individual, object or score has an equal chance of being selected with or without replacement. — However, random sampling is usually not possible— Hence non probability sampling has to be used whenever random sampling is not possible
Nonrandom Sampling is: when every individual, object or score DOES NOT has an equal chance of being chosenTypes of non random sampling:1. Convenience samplinga type of convenience or accidental sampling which relies heavily on available subjects— eg. people walking past certain area2. Judgemental sampling– Based on your knowledge of the population, its elements and your research aims3. …

Positively Skewed or Right Skewed When the mean is more than the median, most of the data is concentrated on the left and hence the data is skewed towards the right. Negatively Skewed or Left …
1. Consists of N identical trailse.g. Throw a dice 20 times 2. Consists of 2 mutually exclusive outcomese.g. head or tail, defective or not defective, success or failureProbability of success is p, probability of failure is 1 – p (which can also be expressed as q) 3. Consists of constant probability for each observation e.g., …
Normal Distribution‘s Characteristics: 1) Symmetrical about the mean (median and mode) a. The mean divides the distribution in two where 50% of the distribution lies below the mean and 50% lies above the mean b. The probability that a score falls below the mean is 50% c. The probability that a score falls above …
