The

Everyday Statistics???

In applying statistics to a scientific, industrial, or societal problem, it is necessary to begin with a population or process to be studied. Populations can be diverse topics such as "all persons living in a country". A population can also be composed of observations of a process at various times, with the data from each observation serving as a different member of the overall group. Data collected about this kind of "population" constitutes what is called a time series.

For practical reasons, a chosen subset of the population called a sample is studied — as opposed to compiling data about the entire group (an operation called census). Once a sample that is representative of the population is determined, data is collected for the sample members in an observational or experimental setting. This data can then be subjected to statistical analysis, serving two related purposes: description and inference.

Mean-add the values of each piece of data then divide by how many total pieces of data there are

KNOWLEDGE (Notes)

Give a personal example of how statistics have influences you or your family at some time in your life.

COMPREHENSION (notes)

Generate a list of real life times and events that require the use of statistics in the making decisions and/or reporting results. Compare and contrast any two of these items on your list.
