[Audio] Correlation Analysis:-In terms of market research, this means that correlation analysis is used to analyze quantitative data gathered from research methods such as surveys and polls, to identify whether there are any significant connections, patterns, or trends between the two. Correlation Coefficient:- It operates under the assumption that the data being used is ordinal, which here means that the numbers do not indicate quantity, but rather they signify a position of place of the subject's standing. If the correlation coefficient is greater than zero, it is a positive relationship. Conversely, if the value is less than zero, it is a negative relationship. A value of zero indicates that there is no relationship between the two variables..

[Audio] What is then required is to fully specify both the deviated and un-deviated conditions, and then compare the two so that changes or differences can be identified. Any change identified in this process thus becomes a candidate cause of the overall deviation. Change analysis is heavily dependent on comparison with similar situations. However, there are varying degrees of similarity, depending on how close the un-deviated condition is to the deviation under investigation. The best-case scenario for change analysis is when you have the previous operational history for the exact same task or operation. In this case, changes or differences that could have contributed to the deviation are easily identifiable.

[Audio] There is a wide range of techniques and tools used in outlier analysis. However, it's often very easy to spot outlying data points. As a result, there's really no excuse not to perform outlier analysis on any and all datasets. t improves the quality of the dataset being subject to analysis. Of course, this in turn brings benefits. With a higher-quality dataset, analysts can expect to draw more accurate conclusions (and more of them). There are a wide variety of techniques that can be used to identify outliers in datasets. Some of the techniques that are used to find the outliers are like sorting, graphing, Z-scores, etc..
