________ means that the observed differences between scores is probably not due to chance variation between the samples.a) The rangeb) Statistical significancec) Standard deviationd) The normal curve

Answers

Answer 1

Statistical significance refers to the likelihood that the differences observed between scores or outcomes in a study or experiment are not due to random chance or sampling variability.

It is a measure of the confidence we have in the results obtained. When results are statistically significant, it suggests that the observed differences are likely to be a result of the variables being studied and not just due to random fluctuations.

To determine statistical significance, statistical tests are conducted, such as t-tests, chi-square tests, or ANOVA (analysis of variance). These tests compare the observed data to a null hypothesis, which assumes that there is no true difference or relationship between variables in the population. If the p-value associated with the statistical test is below a predetermined threshold (usually 0.05), the results are considered statistically significant, and we reject the null hypothesis in favor of the alternative hypothesis.

In summary, statistical significance provides evidence that the observed differences or relationships in data are likely to be meaningful and not just a result of random chance.

If the Artic Circle measures at 66° 30' north latitude, what is
measurement for the Antarctic Circle?

Answers

At 66°30′ S, the Antarctic Circle is a parallel or line of latitude encircling the globe.

Why are the Antarctic Circle and Arctic Circle located at 66.5 N and 66.5 S, respectively?

The Earth's rotational axis is tilted by 23.5 degrees, hence the angle of 66.5 degrees is equal to 90 degrees minus 23.5 degrees.

The method for measuring latitude lines

The line with a latitude of 0 degrees is the Equator. There are nine parallels, each one a degree north or south of the equator, with the equator at 90 degrees in both directions. The North Pole is located at latitude 90 degrees N, whereas the South Pole is located at latitude 90 degrees S.

Beliefs are formed once then it takes stronger evidence to modify them than it did to create them. This is statement true.

An attitude that something is the case or that a proposition is true is called a belief. In epistemology, philosophers refer to attitudes toward the universe that can either be true or wrong as "beliefs."

To take something as true means to believe it to be true; for example, accepting the truth of the statement "snow is white" is equivalent to believing that snow is white.

Contemporary philosophers have attempted to define beliefs in a variety of ways, including as models of how the world might be, as propensities to act as though certain things are true, as interpretive frameworks for understanding someone else's actions, or as mental states that serve a specific purpose.

Carl Jung's study of introversion-extraversion launched the trait approach, which focuses on identifying, measuring, and comparing stable personality traits. This approach has paved the way for extensive research in the field of personality psychology.

The term that Carl Jung helped launch the trait approach with is the study of "introversion-extraversion."Carl Jung was a Swiss psychiatrist and psychoanalyst who helped launch the trait approach with the study of introversion-extraversion.

It assumes that individuals possess relatively stable personality characteristics that can be measured, predicted, and compared with others. The introduction of the introversion-extraversion trait by Carl Jung paved the way for subsequent trait research.

Trait researchers began to explore other personality dimensions, such as neuroticism, conscientiousness, openness to experience, and agreeableness. The trait approach has been widely used in psychology, particularly in the field of personality psychology.

What happens during El Nino? During El Niño, air pressure rises in the western Pacific
and falls in the central and eastern Pacific. Without the strong pressure gradient, the
trade winds weaken. Without the trade winds, there is less upwelling near the coast of
South America and the warm and nutrient-poor water of the western Pacific spreads
east, piling up water in the eastern tropical Pacific. Not as much marine life can survive
in the warm water as can in the cool nutrient-rich waters. The warm water in the Pacific
evaporates faster than cool water, leading to more water vapor in the air which can
cause high humidity.

El Nino causes significant weather changes in the Pacific as well produces significant changes in marine life.

What is El Nino?

El Nino is an abnormal weather pattern which occurs as a result of the warming of the Pacific Ocean near the equator, off the coast of South America.

During El Nino, air pressure rises in the western Pacific and falls in the central and eastern Pacific, thus weakening normal trade winds.

Less upwelling occurs near the coast of South America and the warm and nutrient-poor water of the western Pacific spreads east, piling up water in the eastern tropical Pacific.

Faster evaporation of warm water in the Pacifc leads to high humidity.

Certain areas in the northern U.S. and Canada are dryer and warmer than usual whereas areas in the U.S. Gulf Coast and Southeast are wetter than usual and have increased flooding.

Also, less upwelling results in fewer phytoplankton off the coast which lowers fish population which in turn, affects everything that eats fish.

Therefore, El Nino causes significant weather changes in the Pacific.
