Description
Computer is an electronic and digital device, it take data as input, process it and gives information as output and save it. Computer is used because it is more efficient and effective. Computer hardware is accessed through Software (operating System) computer is Extensible: means we can add any number of application software to this and extend its functionality. Versatile : means it is used in almost all places like hospitals, business, education, Research etc. Computer is not similar to any other electronic and digital machine but its Versatile and Extensible.
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 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.
