The Three Chosen Variables are “tlifesat,” “tslfest" and "agegp5" (Statistics Project Sample)

The Three Chosen Variables are “tlifesat,” “tslfest" and "agegp5" 

The three chosen variables are “tlifesat,” “tslfest" and "agegp5," which represent the total life satisfaction, total self-esteem, and age-5-groups. The first two variables, that is, the variables that represent the total life satisfaction and the one that represents total self-esteem are measured in interval scale. From the look of the data, the figures might have been read from a scale and recorded in order. The third variable showing the age group is a normal variable. The reason is, different numbers have been assigned to represent the age groups. For example, 1 represent age group of between age 18 to 24, 2 represent age 25 to 32, 3 represent 33 to 40 years, 4 represent 41 to 49, and 5 represent ages above 50. A descriptive summary of the variables is given in Table 1 below.
