Explanation:

Statistics divide in descriptive,predictive, inferences.Descriptive statistics is to describe the data.Predictive is to expect the future.Inference is to find the sample of conclusion or reasoning.In order to find a predictive model, 1st we need to apply.Association rule, One variable in relationship with other.Strong positive Correlation,No correlation, weak correlation, negative,weak negative correlation.1.00 is strong correlation and -1.00 is negative correlation.Negative correlation means as y axis is increasing x axis is decreasing.Scatter plot is the best example to give positive or negative correlation.It is easier to create a trend line also.
