Tweet In the previous post introducing governance we ended by observing a roughly pyramidal order in every organization. Yet in my mental model I visualize the 7.4 billion people on Earth as individual bubbles engaged in pedesis or Brownian motion. First observed, or at least documented, by botanist Robert Brown in 1827, he observed that the triangular […]

## Statistics (and Probability) – Part Ten

Tweet In the previous posts we explored different areas where statistics are used for scientific purposes, management purposes. operational decisions and intellectual purposes. For example, measuring the cross sections of a Uranium atom (a statistical measurement) allows for the design of a nuclear reactor. But how do you measure what people want both individually and collectively? […]

## Statistics (and Probability) – Part Nine

Tweet In the previous post we surveyed some of the areas where statistics are essential in the disciplines, ending that there was insufficient space to cover statistics in governance. While governance covers a broad range of activities, for now let us just explore government and, more specifically, a democracy. In democracy, citizens vote on who should […]

## Statistics (and Probability) – Part Eight

Tweet In this series we have looked at the application of statistics in a few areas with the central theme that statistics deals with the representation of large volumes of historical data points in order to make predictions about the future and decisions about what path or road to take. We know where to go […]

## Statistics (and Probability) – Part Seven

Tweet We finished Part Six of this series by referencing the terms mean, mode and median. What do these terms tell us statistically? To explore them, consider the following fictional set of data about the appraised value of a set of houses in a small cluster of homes. Number of Houses Value ($K) 1 […]

## Statistics (and Probability) – Part Six

Tweet In the previous part of this series, we identified several areas where statistics play a major role in the decision making and management of a field or industry. Moving to greater detail, a good place to start is insurance, something we all purchase based on fear or required by law. In 1653, Lorenzo de […]

## Statistics (and Probability) – Part Five

Tweet In the previous part of this series we looked at baseball and the emergence and growth of statistics in the game. From a casual perspective, a player’s batting average tells you, to three decimal places, the historical probability of getting a hit (getting on base by hitting the ball in fair territory) the next […]

## Statistics (and Probability) – Part Four

Tweet In the previous column (Part Three) we ended with a question about statistics and its uses – investing, making money, providing governance, managing the budget, making choices, or something else. As an example, consider baseball, professional baseball. For the vast majority of us, baseball is a form of entertainment as well as a sometimes […]

## Statistics (and Probability) – Part Three

Tweet At the end of part two of this series, two charts on deaths in the United States (reproduced below) were presented and I asked the question “What do they tell you?” These charts present data (statistics) from two sources for the year 2013, which is not indicated on the graphics. The […]

## Statistics (and Probability) – Part Two

Tweet In the previous post we looked at nuclear cross sections as the probability of a nuclear interaction and noted that the cross section is a statistic derived through experimentation. If the statistic was measured incorrectly, the nuclear reactor would fizzle and a mess would result. But what if the measurement dealt with people and was […]
