How to Spot Patterns of Association in Data Tables - The majority of the advanced analytics depends on the skill of identifying patterns in the data. For example, whether there is any link that exists between two or more variables or whether a particular group is showing some attributes. Patterns are identified to generalize a conclusion on a wide population. A pattern is usually something repeats itself again and again or a process that is taking place at regular intervals. Suppose you have a group of males that like ice cream and a group of females that like ice cream too. You see that all males under the age of 18 eat ice cream more than 10 times a week while the patten for females under the age of 18 eats it 20 times. For all individuals over the age of 18, the preference for eating ice cream is more or less the same. It can be identified that females have more likeness towards ice cream than men. This observation was made based on the pattern that was seen on the provided data.
