AC MEASUREMENT This chapter explains rectification for measurement and rectifying instruments. Knowledge of the circuit principles will help you use these instruments properly and measurements alternating current correctly. One of the most common and economical methods for measuring alternating currents is to rectify these currents and read the resultant DC on an analog or digital volt-ohm meter (VOM). You need to take many considerations into account when using rectification: what type of rectification

for razor blades (is it?)‚ or that your SSN is higher than mine ( is it?) tells us nothing. In surveys they often use arbitrary numbers to code variables such as religion‚ ethnicity‚ major in college or gender. In fact‚ with nominal variables measurement means: classifying cases in (unordered) groups. (A group can have a single member‚ as it is the case with SSN.) The groups must be --- all-inclusive: they must cover all cases --- mutually exclusive: each case must belong to one and only one group

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy

ATTITUDE MEASUREMENT Attitudes are expressions of our covert feelings about or toward an object‚ person‚ issue‚ event‚ or behavior. An attitude is a point of view about a situation. It is generally agreed that attitude can be defined as a learned disposition or tendency to respond in a consistently favorable or unfavorable manner with respect to a given object. One similar definition given by Baron and Byrne for attitudes is: relatively lasting clusters of feelings‚ beliefs‚ and behavior tendencies

Nominal Level of Measurement The nominal level of measurement is the lowest of the four ways to characterize data. Nominal means "in name only" and that should help to remember what this level is all about. Nominal data deals with names‚ categories‚ or labels. Data at the nominal level is qualitative. Colors of eyes‚ yes or no responses to a survey‚ and favorite breakfast cereal all deal with the nominal level of measurement. Even some things with numbers associated with them‚ such as a number
