There are various bits and items of folklore in arithmetic which are handed down from consultant to pupil, or from collaborator to collaborator, yet that are too fuzzy and non-rigorous to be mentioned within the formal literature. routinely, it was once a question of good fortune and site as to who discovered such folklore arithmetic.

Both notations are acceptable as long as the notation is consistent throughout a publication. Don’t use more than one forward slash: Epot /kJ mol−1 is OK, but Epot /kJ/mol is not! Of course there are several plotting programs to realize fancy graphics on a computer, but in many cases a quick sketch by hand on graph paper suffices to get a crude idea of a functional relationship and the importance of inaccuracies. 5 on page 172 to produce Fig. 7 with a logarithmic scale. Summary In this chapter you have seen how experimental results are properly presented in a report or publication.

E. an uncertainty of 1 percent. 4 The probability that exactly k events are observed in a given time interval, when the events arrive randomly with an average of 3 per time interval. d. μ. 4 shows the probability f (k) of observing k events when the mean number μ = 3. For example, a specialized hospital ward admits on the average 3 urgent patients per day; f (k) is the probability that on a given day k patients arrive, assuming the patients arrive randomly. 6. 5 The normal distribution See data sheet NORMAL DISTRIBUTION on page 205.

The “sender” sequentially selects cards from a well-mixed pack of “Zener cards,” which contains an equal number of five types of card (each with a simple figure: square, circle, cross, star, wavy lines) and concentrates for a moment on the figure; the “receiver” notes which card he thinks has been drawn, without being able to see the card. One such experiment involves 25 cards. 2 and on average 5 cards will be guessed correctly. 1 The binomial survival function 1 − F(k), giving the probability that more than k Zener cards are guessed correctly out of 25 trials.
