a histogram is to "bin" the data range, or divide it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. The bins must be close together and are frequently the same size....
In marketing research, as well as other forms of social, economic and business research, interval and ratio data are king.
INTEGER data type The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. INTERVAL data type The INTERVAL data type stores a value that represents a span of time. INTERVAL types are divided into two classes: year-mo...
Math functions do exactly as you would expect. They allow you to add, subtract, multiply, and perform other similar functions. Also, Math functions allow you to find the smallest and largest numbers from a data set or get a random number between a specified interval, among other things. To...
