Quantitative Data

A sample of 40 female statistics students were
asked how many times they cried in the previous
month.Their replies were as follows:

Stem-Leaf Plot
A natural way to organize (group) quantitative data is with the order property of the real numbers, i.e., arrange the data from least to greatest. For example, the 30 weights: 185, 160, 235, 165, 125, 175, 185, 132, 168, 112, 170, 155, 105, 158, 120, 190, 140, 185, 125, 180, 145, 110, 155 135, 170, 113, 155, 175, 145, 130 are more easily comprehended in order: 105, 110, 112, 113, 120, 125, 125, 130, 132, 135, 140, 145, 145, 155, 155, 155, 158, 160, 165, 168, 170, 170, 175, 175, 180, 185, 185, 185, 190, 235. Note that each weight has been listed as many times as it occurs. This information can be visually presented with a stem and leaf plot. A position has been chosen to break the numbers into a stem and a leaf. The leaf will always be one digit. The stems are listed on the left, and the corresponding leaves (if any) on the right. Visually a stem-and leaf plot looks like a bar chart; the categories are defined by the decimal structure of the numbers. A stem-and leaf plot for the above data is presented below:

...assume that all the relevant input
data are known with certainty. That is, these models
assume that all the information needed for modeling the
decision-making problem environment is available, with
fixed and known values
For example, deciding how many sections of a course to
offer during a semester can be modeled as a deterministic
model since the costs and benefits of offering each section
are known. The most commonly used deterministic

...Question1
Quantitativedata are measures of values or counts and are expressed as numbers (www.abs.gov.au). In other words, quantitativedata are data about numeric variables (www.abs.gov.au). Four types of quantitativedata are interval, nominal, ordinal and ratio.
Firstly, interval scales are numeric scales in which we know not only the order, but also the exact differences between the values...
