Market research plays an integral role in effectively developing business strategies to target the right markets for your product. Accurate market research can be gathered by conducting studies. In some studies, you will need to find chisquared values  a comparison between observed and expected results  to determine if your findings are significant. Significance, in market research terms, means that your findings are most likely accurate. When your data is displayed in a bell curve, you can find the lower and upper values of your study. When you are finding both values, it is referred to as a twotailed test. A lefttailed test refers to the left side of the bell curve, or lower limits, of the data. On the other side, a righttailed test allows you to find the upper limits of your data.
Things You'll Need
 Chisquared table

Look on your chisquared table in the left column to find your degrees of freedom. Degrees of freedom are parameters used when testing a hypothesis, and are based upon the data from your study.

Locate your significance value along the top of the chart. This value, like the degrees of freedom, varies with each study. The significance value represents the likelihood that your critical value will be exceeded

Find the intersecting numbers from your degrees of freedom and significance value. This value is your critical chisquared value for a righttailed test.
