The z-score is defined as the number of standard deviations that separate a certain observed value from the population mean. The larger the z-score, the further the observed value is from the mean, and the more unusual. Z-score will be positive if the value is located above the mean and negative if located below.

As the formula in the picture indicates, the z-score is computed from the observed or raw value by substracting the mean and by dividing the number obtained by the standard deviation afterwards. The result is the z-score with a mean of 0 and standard deviation of 1, and it can be represented in the normal distribution (picture 2).

Which right and responsibility is the most important in society?

ArbitrLikvidat [17]

The concept of a right relates to the freedom from interference by other individuals or the government. Individual rights refer to the liberties of each individual to pursue life and goals without interference from other individuals or the government. Examples of individual rights include the right to life, liberty and the pursuit of happiness as stated in the United States Declaration of Independence.

A community is a group of people with common interests and values. Community is characterized by "wholeness incorporating diversity" and may include people of different ages, ethnicities, educational backgrounds and incomes (Gardner 2003). Individuals may be members of two or more communities; for example, one of geographic residence and another of employment.

Community responsibilities are an individual's duties or obligations to the community and include cooperation, respect and participation. The concept goes beyond thinking and acting as individuals to common beliefs about shared interests and life. A basic community responsibility is voting in elections.

Each individual is part of a larger community. Family, neighbors, tribe, village, city, county, state, region, country and the world form a larger community in the life of every human being. At the same time, full human potential cannot be reached if individuality is suppressed by society.
