Document Summary
We all agree when i say the word two, you picture two things. Knowing 2 and 9 aren"t the same thing. Equal intervals: difference between the units is uniform. The different between 100 and 101 is the same difference between 1 and 2. True zero: which represents a quality of nothing. Discrete variable: separate categories: no values exist between two categories or valu. Continuous variable: infinite number of values fall between each value. Will not b use but w ask abou. 1st vs 2nd- you know that 1st place. 15 and 16 is the same difference between 30 values ot be tested on the but will about the scales. 15 and 16 is the same difference between 30. No true zero: has a negative unless using kalvin. Ex: counting the people in a room, height, weight. Height has a true zero because you start a 0 at. Can do things like multiple/ divide saying you have.
