Description
A good theory is a way of making sense of a disturbing situation. To engage in theorizing means to take thought about what is there to be learned. Theories are explanations based on observations and reasoning.
Below is the document preview.
LESSON 4: MEASURES OF DISPERSION
Trending!
The measures of central tendency are not sufficient measures to reveal the shape of the distribution of data set. The measures that show the spread of a data set are called the measures of dispersion. The main measures of dispersion are range, inter quartile range, standard deviation, variance and coefficient of variation. In this lesson we will discuss these measures of dispersion.

LESSON 2: MEASURES OF CENTRAL TENDENCY
Trending!
One of main objectives of statistical analysis is to obtain one single value that describes the characteristic of the entire mass of unwieldy data. Such a value is called the central value or average value. In this lesson we will consider some of central values which are commonly used.

LESSON 6: SKEWNESS AND KURTOSIS
Trending!
Skewness refers to lack of symmetry. A skewed distribution is a frequency distribution that is asymmetric (not symmetric). When the longer tail of a distribution extends to the right, it is said to be skewed to the right and when the longer tail of a distribution extends to the left, it said to be skewed to the left.
