WebSep 18, 2024 · Interval data is measured along a numerical scale that has equal distances between adjacent values. These distances are called ‘intervals’. There is no true zero on an interval scale, which is what distinguishes it from a ratio scale. On an interval scale, zero is an arbitrary point, not a complete absence of the variable. WebApr 2, 2024 · A frequency is the number of times a value of the data occurs. According to Table Table 1.4. 1, there are three students who work two hours, five students who work three hours, and so on. The sum of the values in the frequency column, 20, represents the total number of students included in the sample. WebThe interval scale is a quantitative measurement scale where there is order, the difference between the two variables is meaningful and equal, and the presence of zero is arbitrary. It measures variables that exist along a common scale at equal intervals. The measures used to calculate the distance between the variables are highly reliable. the paper boat kenmore
