How to estimate standard deviation from a histogram.

Answers

Answer 1

Estimating the standard deviation from a histogram involves using formulas to get an estimate of the standard deviation. The standard deviation measures the degree to which data points vary from the mean of a data set. It is calculated as the square root of the variance of a data set.

How to estimate standard deviation from a histogramThe process of estimating standard deviation from a histogram involves the following steps:Step 1: Construct a histogram of the data setStep 2: Calculate the mean of the data setStep 3: Calculate the variance of the data set by using the formula below: Variance = ∑(x - μ)²/n Where x represents the data point, μ is the mean of the data set, and n is the sample sizeStep 4: Take the square root of the variance calculated in step 3 to obtain the standard deviation.

The formula for calculating standard deviation from the variance is: Standard deviation = √VarianceWhere variance is represented by the symbol σ².TThe mean is used as a measure of central tendency, and the standard deviation is used as a measure of variation.In conclusion, estimating the standard deviation from a histogram involves calculating the mean and variance of a data set, and then taking the square root of the variance to obtain the standard deviation.

3. 2. Critically discuss THREE links between unemployment and crime / lack


of self-esteem.

Answers

There are three key links between unemployment and crime/lack of self-esteem: economic strain, social disintegration, and psychological impact.

The first link between unemployment and crime/lack of self-esteem is economic strain. Unemployment often brings financial difficulties, making it challenging for individuals to meet their basic needs. Economic strain can lead to desperation, increasing the likelihood of engaging in criminal activities as a means of survival. Individuals may resort to theft, fraud, or other illegal means to obtain resources and alleviate their financial strain.

The second link is social disintegration. Unemployment can erode social bonds and disrupt community cohesion. Joblessness can lead to social isolation, as individuals may withdraw from social activities due to feelings of shame, embarrassment, or exclusion. This social disintegration creates an environment where criminal behavior may thrive, as social support networks weaken, and individuals become disconnected from positive influences.

The third link is the psychological impact of unemployment on self-esteem. Job loss can significantly impact an individual's self-worth and identity. Unemployment can lead to feelings of worthlessness, failure, and frustration, which can contribute to low self-esteem. A lack of self-esteem increases vulnerability to negative influences and can diminish the motivation to engage in prosocial activities. This diminished self-esteem can make individuals more susceptible to engaging in criminal behavior as they seek validation, power, or control.

These three links between unemployment and crime/lack of self-esteem highlight the complex interplay between socio-economic factors, individual psychology, and criminal behavior. Addressing unemployment and its associated consequences is crucial for reducing crime rates and promoting positive self-esteem within communities.

In Plessy v. Ferguson case, the Supreme Court denied that segregated railroad cars for Black people were necessarily inferior. The Supreme court called the logic in Plessy’s argument a fallacy.

What was the famous Plessy v. Ferguson case?

A Louisiana law "providing for separate railway cars for the White and Colored Races" that was enacted in 1890, was at the center of the case that would become Plessy v. Ferguson. These distinct cars, which were to have similar amenities, had to be provided by all passenger railroads, according to the law.

The ruling in Plessy v. Ferguson was handed down by the Supreme Court on May 18, 1896. The Court concluded that the 14th Amendment's safeguards only extended to political and civil rights (such as voting and jury duty), not "social rights (sitting in the car of your choice)," while determining that separate-but-equal facilities on intrastate trains were constitutional. The Court rejected the idea that Black people's segregated train cars were inherently inferior in its decision.

Answers

Answer:

Examples

Explanation:

George Orwell uses examples - 'millions of peasants are robbed of their farms', 'people are imprisoned for years without ot trial or shot in the back of the neck.

These are all examples he uses to support his claim of 'political speech and writing are largely the defense of the indefensibe' but using examples of the indefensible.

In the passage, George Orwell primarily uses examples and facts to support the claim that "political speech and writing are largely the defense of the indefensible."

While statistics and quotations are not explicitly mentioned in the question, they can be considered subsets of examples and facts.

Orwell provides examples of specific political statements and writings that attempt to justify or defend actions that are morally or logically indefensible. He mentions phrases such as "pacification of the East," "liquidation of the kulaks," and "rectification of frontiers" as instances where political language is used to hide the true nature of oppressive actions.

By presenting these examples, Orwell illustrates how politicians and writers manipulate language to obfuscate the reality of their policies and actions. He argues that political language is often used to disguise or distort the truth, creating a defense for actions that would otherwise be seen as morally or intellectually indefensible.

While statistics and quotations can also serve as evidence to support such a claim, they are not explicitly mentioned in the passage provided. However, if there were specific statistics or quotations used by Orwell in the broader context of his work, they could be considered additional types of evidence to bolster his argument.

The Schachter-Singer Theory

Like the James-Lange theory, the Schachter-Singer theory states that people do infer emotions based on physiological responses. That is, the critical factor is usually the case or situation on ground while the cognitive interpretation is what individuals use to label that emotion.

When compared to the Cannon-Bard theory, the Schachter-Singer theory also state that similar physiological responses can produce different emotions. For example, if you experience a racing heart and sweating palms during an important english exam, you may also identify the emotion as anxiety. If you experience the same physical responses on a date with your significant person, you might interpret those responses as love, affection, or arousal.

Compare and contrast the drive-reduction theory and the incentive theory of motivation.

Answers

The study of what motivates a person to work toward a specific goal or end is known as motivation theory.

What is the Drive-reduction and Incentive theory of Motivation?

According to the incentive theory of motivation, external forces such as reward or punishment serve as a driving force that encourages humans to act.

External forces motivate a person to do a task or activity in order to receive a reward or avoid punishment.

According to the drive-reduction idea, a person's internal biological demands cause them to act.

If these biological requirements are unsatisfied, they generate internal conflict, such as hunger. These biological demands function as a motivating factor.

Both ideas try to explain what motivates people's personal actions.

Internal states of stress encourage humans to behave, according to the drive-reduction hypothesis of motivation. It also portrays the source of motivation as being within the organism, similar to how hunger and weariness are within us.

However, the incentive theory of motivation explains how external factors compel people to act, and it portrays the source of motivation as being outside of the organism, such as how rewards and penalties are external.
