FUND. MATHS - UNIT 2 STUDY AREA 1- UNIVARIATE STATISTICS 2.3. SINGLE-VALUED CLASSES If only a few unique values occur in a set of data, the classes are expressed as a single value rather than an interval of values. This is typically occurs with discrete data but may also occur with continuous data because of measurement constrains. Example: A quality technician selects 25 bars of soap from the daily production. The weights in ounces of the 25 bars are as follows: 4.75 4.74 4.74 4.77 4.73 4.75 4.76 4.77 4.72 4.75 4.77 4.74 4.75 4.77 4.72 4.74 4.75 4.74 4.76 4.75 4.74 4.75 4.77 4.75 4.75 w many unique values are there? can use in this single-valued classes.
