Question

2. Given the following data (in increasing order) for the attribute age: 13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25, 25, 25, 30, 33, 33, 35, 35, 35, 35, 36, 40, 45, 46, 52, 70.
 Categorize using a bin depth of 3 and smooth by bin means. Illustrate your steps. Comment on the effect of this technique for the given data.
 What other methods are there for data smoothing?
 How might you determine outliers in the data?
 Normalize the values of the attributes to the range

Answer 1

Answer:

The age values for the data tuples are (in increasing order): 13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25, 25, 25, 30, 33, 33, 35, 35, 35, 35, 36, 40, 45, 46, 52, 70. (a) Use smoothing by bin means to smooth the above data, using a bin depth of 3. Illustrate your steps.
