Figure 1. On many standardized assessments the publishers base the standard score on a distribution with a mean of 100 and a standard deviation of 15. A score of 100 on such a test (e.g., WJIIIDRB) means that if the student scored in the middle of the distribution (Mercer & Pullen, 2009). standard score is based on a normal distrbution with a mean and a standard deviation (see Figure 1). The black line at the center of the distribution represents the mean. The turquoise lines represent standard deviations. Figure 1.
Labor unions have a long and colorful history in the United States. To some people, they conjure up thoughts of organized crime and gangsters like Jimmy Hoffa. To others, labor unions represent solidarity among the working classes, bringing people together across many professions to lobby for better rights, wages and benefits.
As a worker, you have a right under federal law to form a union, select representatives of your choice and bargain collectively with your employer. This helps balance the power that employers have over individual employees. Belonging to a union gives you rights under law that you do not have as an individual.
