Section 1: Introduction
Understanding and Implementation of ANOVA
ANOVA is a group of statistical models which is used to test the significant difference between means. It finds out whether the means of various groups are equal or not. Here the differences are found by comparing the variances. Before ANOVA the t-test and z test were used. But then in 1918 ANOVA was developed by Ronald Fisher. ANOVA can be used to test the various null hypothesis at the same time. ANOVA can be used for various purposes by various persons. Researchers use ANOVA in three ways – one way ANOVA, two way ANOVA and N way Multivariate ANOVA. This chapter explains to you the basic of ANOVA and its implementation.
Pairwise comparison is used to compare the entities in pairs to find out which of the entities are identical and which of the entities are not identical. This chapter will help you to learn how to test the differences among means. The other topics included in this section are

Features of Chi-Test
The Chi-square distribution was first used by Karl Pearson in the year 1900. The chi-square distribution is the distribution of a sum of squares of k independent standard normal random variables with k degree of freedom. The null hypothesis in Chi-square test is that the distribution of the test statistics is a chi-square distribution and it is true. The chi-square test is used to find test the goodness of fit. Chi-square test can be used on nominal data. It is easy to calculate and interpret. The detailed explanation of chi-square test along with its examples are given in this chapter
Under this chapter, a sample research problem is given to illustrate repeated measures ANOVA. In this example, the researcher wants to examine the impact of dietary habit and exercise on the pulse rate of the sample. This example answers the following questions
Does intensity influence pulse rate?
Does dietary preference influence pulse rate?
Does the exercise type on pulse rate depend on dietary preference?
Does the influence of diet on pulse rate depend on intensity?
Difference between Growth Plan and Dividend Plan in MF
When selecting a mutual fund an investor has n number of choices. The more tough decision is to choose between the fund with growth option and the fund with dividend reinvestment option. Each type of fund definitely has its own advantages and disadvantages. And deciding which type of fund to choose purely depends on the individual needs and purposes.
In the growth option, the investor will have the same number of units in the end as it was in the beginning. The investor will not receive any dividends that will be paid out of the stocks. The growth option will not suit the investors who want to receive regular profits from their investment. The growth option is the best way for the investors to increase their Net Asset Value (NAV).
The dividend reimbursement option is different from the growth option. In mutual funds, some amount will be paid to the investors every year which is called dividend. This amount is paid to the investors to help them purchase more shares. The fund administrator purchases few more shares with that amount on behalf of the investor and will transfer them to the investor’s account.
The other differences between the growth option and dividend option in are explained in detail under this lesson
Checking NAV Price and Repurchase Price
Net Asset Value (NAV) is the actual value of a single unit of a given scheme. The NAV is the liquidation value of the fund on that particular day. The NAV is calculated by deducting the liabilities from the value of all the assets. Then it is divided by the number of units which is outstanding.
A close-ended fund has a fixed maturity period that varies between 2 and 14 years. Close-ended funds sell only a fixed number of shares in the initial offering and the remaining shares are sold in the secondary market. The cost at which the shares are sold in the secondary market is totally based on the market and not on the NAV. The repurchase price is the price at which the investors sell back the units to the mutual fund. It is NAV related and can also include the exit load.
