Sampling and Measures of Central Tendency and Dispersion Introduction: Overall Job Satisfaction (OJS) was the variable selected for this exercise because it lends itself to measures of central tendency and dispersion. The data are quantitative and continuous in nature. Data Selected: The instructions for the exercise suggested a sample of approximately 30 individuals from one of eight variables. There were 288 measures of OJS. Every ninth individual was selected resulting in thirty-two

1 Measures of Central Tendency “Measures of central tendency (averages) are statistical constants which enable us to figure out in a single effort the significance of the whole.” (Prof Bowley) The main objectives of measure of central tendency are To reduce data in a single value. To make easy comparisons between data. There are different types of averages; each has its own business applications. 1. Arithmetic Mean 2. Median 3. Mode 4. Geometric Mean 5. Harmonic Mean 1.1 Arithmetic

One of the great discoveries made by Dr. Montessori was that all humans have certain tendencies or behavior patterns. No matter where we live‚ no matter our culture or ethnicity‚ we all follow the same natural laws that lead us to act or react in a specific manner. We are all driven to: Communicate Socialize Imitate Explore (we are curious) Move Be exact/precise Concentrate Repeat Maintain/discover order Achieve independence Realize perfection/Control errors/Improve ourselves Control
