  1. Section 3.1 Measures of Central Tendency

pH in Water:

The acidity of alkalinity of a solution is measured using pH. A pH less than 7 is acidic; a pH greater than 7 is alkaline. The following data represent the pH in samples of bottled water and tap water.

The pH of a liquid is a measure of its acidity or alkalinity. Pure water was a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are alkaline. A biologist was interested in testing the purity of lake water in Florida. A random sample of 59 lakes was taken, and the pH of water in each lake was recorded. The sample of lakes had an average...

Fresh water from rivers and lakes varies in acidity/alkalinity depending on the rocks and soils it runs over. Granite country yields water that is slightly acidic, while water from limestone country is slightly alkaline. Acidity and alkalinity are measured on a pH scale, on which 7 is neutral, values below 7 are acidic and values above 7 are alkaline. pH can change due to pollution or due to waste from biomass such as algae. A certain river, fed by various...

The three main measures of central tendency are the mean, median, and mode. Each of these could be impacted in different ways by an outlier that is distant from the other data points. Depending on the data set that you are describing, you might choose to use the mean, median, or mode to give a more accurate view of the data.   Describe a situation where you might have an outlier in a data set. How will this outlier impact the...

The mean, median, and mode are frequently referred to as the measures of central tendency. All three of these are used commonly, especially by the media when trying to make a point or persuade an audience to some point of view. However, each of these three statistical measures has their own shortcomings.
