Effect of Prior Information on String Length Estimate p.66
Christine A Franklin & Madhuri S Mulekar
This article describes an activity through which students collect data and
explore ways to display them through graphs and charts. It also motivates
various summary measures for location, spread and shape. Finally it gives
an introduction to concepts of validity, reliability and bias.
What are the Chances? p. 72 Danny Helman
A lottery coincidence provides the background for discussing the assessment
of probabilities and the definition of events.
COMPUTING CORNER
Chernoff Faces in Microsoft Excel p. 752 Neville
Hunt
This article describes how Chernoff faces can be drawn in Microsoft Excel.
Line fitting with Outliers p. 78 Elizabeth M Glaister
& Paul Glaister
This article illustrates a method for fitting straight line data that
is resistant to outliers and might therefore sometimes be preferred to the
customary least squares procedure..
The Most Compact Subdomain of a Continuous Probability Distribution
p. 81 David Farnsworth
This article describes the most compact 100c% interval for a probability density
for 0 <c < 1. An unbiased, distribution-free estimator when c = 0.5
is presented.
Great Expectations p.84 Neil Sheldon
This article introduces the concept of a prediction interval in a gambling
context.,
Investigating Probabilistic Intuitions p. 86 Robert
J Quinn
This article explores the intuitions of secondary education majors regarding
probability. This is accomplished by administering a two-question instrument
to 113 participants. Their responses to these questions, and more importantly
the explanations they provide for these answers, are analysed. The conclusions
drawn may be informative to teachers of probability and statistics as they
attempt to remediate common probabilistic misconceptions and devise more effective
teaching strategies.
A Lower Bound for the Most Deviant Z-Score p. 89 Frederick
Wiseman
This article demonstrates that the lower bound for the most deviant z-score
and the upper bound for the sample standard deviation are attained simultaneously.
A Further Coin Tossing Experiment. p. 92 K S Bhanu &
M N Deshpande
In this note, a coin-tossing experiment which leads to three discrete
distributions is discussed.
