As big data continues down its path of growth, there is no doubt that these innovative approaches  utilizing NoSQL database architecture and Hadoop software  will be central to allowing companies reach full potential with data.
This is a predictive confidence interval in the sense that if one uses a quantile range of 100p%, then on repeated applications of this computation, the future observation X n + 1 {\displaystyle X_{n+1}} will fall in the predicted interval 100p% of the time.
The frequency of a class interval is the number of observations that occur in a particular predefined interval. So, for example, if 20 people aged 5 to 9 appear in our study's data, the frequency for the 5â9 interval is 20. The endpoints of a class interval are the lowest and highest values that a variable can take.
