Graphical Presentation of Data

Michaehs-Menten equation is a segment of a rectangular hyperbola showing a saturation kinetics (Fig. 4). From the direct plot of Vo versus [substrate] in Fig. 4, it is difficult to determine Ae kinetic parameters and Ka with precision, and a 

The Michaelis-Menten equation can be cast in several linear transformations in practice, the most popular are the following

Graphical presentation of data assists in determining the form of the function of a single variable (or two variables). The response y versus the independent variable x can be plotted and the resulting form of the model evaluated visually. Figure 2.4 shows experimental heat transfer data plotted on log-log coordinates. The plot... 

In addition, in the graphical presentation of data, different conventions are used, giving rise to problems in the interpretation and comparison of results. However, a good convention will not cause any problems. In this book (Fig. 1.2) positive potentials are directed to the right of the origin, and anodic (oxidation) currents are taken as positive (directed upward from the...

Although the facilities offered are often attractive, the learning time required for some of the more complex operations is considerable and they should be considered only for specific purposes routine graphical presentation of data sets is best done from within a spreadsheet or statistical package. There may be a service provided by your institution for the preparation of such material and this should be seriously considered before trying to learn to use these programs. 

The ability of PBO in synergize cholinesterase-inhibiting insecticides has often been ignored when the mode of action of PBO is discussed. Moore field (I95KJ presented detailed data on this subject and showed that both aromatic and heterocyclic carbamates can be potentiated with PBO. A graphical presentation of data is reproduced in Fig. 19.3 on the effect of adding PBO to iwo carbamate insecticides to control house flics. This is of particular interest in that application was only made to female flies by individual measured drops - much more precise and relevant to effective control than spray applications to Hies of both sexes. This was a classic demonstration of the powerful synergistic action of PRO...

Monitor Indicator. Once the indicator is defined, the data-acquisition process identifies the data sources and data elements. As these data are gathered, they must be validated for accuracy and completeness. Multiple indicators can be used for data validation and cross-checking. The use of a computerized database allows rapid access to these data. A database management tool allows quick sorting and organization of these data. Once gathered, these data must be presented in a format suitable for evaluation. Graphic presentation of data allows rapid visual analysis for thresholds, trends, and patterns. 

In both of those editions, spectroscopic correlations are presented essentially in tabular form. It is onr conviction, however, that for spectroscopic data, correlation charts are far more easily used than tables. This is especially true of scientists and students who must make use (occasional or freqnent) of spectroscopic methods, while their own areas of specialization may lie elsewhere. We have therefore developed a set of fundamental correlation charts that target the same audience as the tabnlar format adopted in CRC Handbook of Basic Tables for Chemical Analysis. The exception wonld be the tables that we present here for mass spectrometry, a technique that does not lend itself to graphical presentation of data. It is nevertheless important to have data for this important techniqne covered here, since often multiple techniques, including mass spectrometry, are used for analyses and strnctnral determinations. 

Graphical presentation of data to illustrate trends and comparisons is very useful, e.g. an audit profile graph which shows the scores achieved in prevention, heading by heading. The headings might include, for example, machine grrarding and personal protective eqrripment.
