The formation of the hypothesis test is based on some factors. If the market is in the trending situation, then buy the assets to get the profits. On the other side, when the market is not trending, you will need to reduce the assets. At the time of making the trading a disciplined approach is required. So, hypothesis is the best option to check the effectiveness of hypothesis. Finding the critical values is a daunting task, so you can simply try an online critical values calculator that calculates the critical values of the distributions. Here, we are going to discuss the step by step procedure of hypothesis testing.

## Hypothesis Testing:

Testing of the hypothesis is a systematic method to test the claim or idea about the population. Basically, hypothesis is an assumption that is created about the population parameters.Four basic steps are involved in testing of hypothesis and they’re:

### State the hypothesis:

Stating the hypothesis is the first step of the testing procedure and this step defines the hypothesis as null or alternative hypothesis. If the null hypothesis is rejected, then it is taken as evidence to favor the alternative hypothesis.

### Set the decision criterion:

The criteria for making the decision are based on certain parameters of the datasets. Here, comes the concept normal distribution, significance level, one tailed and two tailed test comes.

#### What is Normal Distribution?

Normal distribution is also called probability distribution in which most of the values lies around the mean of the dataset and the other lies symmetrically above or maybe below the mean.Finding the critical values is a difficult task but for convenience, you can try an online left and right critical value calculator that helps to find the critical values of z, t, chi square, and f distributions.

#### Significance level:

Significance level is used for setting up the criteria on which the decision is made about the null hypothesis. Level of significance is defined as the probability, in which the test statistic reject the null hypothesis if the hypothesis is true. In these distributions, you have an area where you can reject and accept the null hypothesis.

Basically, the critical value is that point where a line separates the distribution in two regions. If you’re confused about critical value calculation, you can simply try the critical value calculator that helps to find the critical values of any tail.

#### One-Tailed test:

One tailed test is used when the rejection region appears on one of the distribution. Z & t critical value table can be used to find critical values of student’s t distribution and z-test. You can also give a try to t &z critical value calculator that helps to understand how to calculate the critical values.

#### Two Tailed test:

In two-tailed test the critical area appears on both sides of the distribution, where the sample is less than or may be greater than the certain range of values.

### Calculate the test statistics:

The most important step of the hypothesis testing is test statistics that decides whether a null hypothesis is accepted or rejected. By using the general formula test statistics can be calculated. Instead of performing the manual calculation, give an account to an online left and right critical value calculator that helps to calculate the t & z critical values according to significance level and degree of freedom.

### Make a Decision:

You’ve have to decide whether the null hypothesis is supported or not. In most of the cases, p-values are used in statistical test to make the decision. Critical values are important to test the data and it is also considered the main factor that assists you to check the validity of the hypothesis. These values are complex to calculate. So, simply use the critical value formula or critical value calculator that allows you to evaluate the critical values of one & two tailed test

**Conclusion:**

You need to have a hypothesis, to create a profitable strategy for trading. The statistical testing is used to determine the validity of the hypothesis. This statistical hypothesis testing is summarized in four simple steps. Usually, testing the hypothesis is considered as the first step before formulating any strategy for trading.
