When a test developer uses the sequential system approach, groups of correlated items are identified as scales?

1 answer:

3 0

The answer is true. In a sequential system approach, if the preliminary test items are selected, testers systematically may inspect results statistically to conclude which items are connected with one another; groups of correlated items are then recognized as scales which are supposed to be comparatively pure measures of definite sizes of mental ability, personality, and etc. The test's value as a valuation instrument that rest on empirical research signifying its consistency and legitimacy.

Answer:Professor Shapiro is supporting the activity theory

Explanation:

The activity theory which is also referred to as the implicit theory of aging states that of elders continue to engage themselves in social groups and activities this will result into optimum level of ageing.

This theory suggest that elders being constantly engaged in social activities will improve their life and slow down the rate of ageing.

N a survey of twelve Harbor Business School graduates, the mean starting salary was $93,000, with a standard deviation of $17,00

scZoUnD [109]

Answer: The confidence interval would be (82198.71, 103801.28).

Explanation:

Since we have given that

Mean = $93,000

Standard deviation = $17,000

n = 12 < 30

So, we will use 't-test' to find the 95% confidence interval,

Here , $\alpha =1-0.095=0.05$

and $n-1=12-1=11$

So, according to t table, we get that

$t_{n-1,\frac{\alpha }{2}}=2.200985$

So, interval would be

$\bar{x}\pm t_{n-1,\frac{\alpha {2}}\dfrac{\sigma}{\sqrt{n}}\\\\=93000\pm 2.200985\times \dfrac{17000}{\sqrt{12}}\\\\=93000\pm 10801.2839\\\\=(93000-10801.2839,93000+10801.2839)\\\\=(82198.71,103801.28)$

Hence, the confidence interval would be (82198.71, 103801.28).

WINSTONCH [101]

Answer:

Interactionist theory

Explanation:

Interactionism is a hypothetical point of view that infers social procedures, (for example, struggle, participation, personality development) from human cooperation. It is the investigation of how people shape society and are molded by society through implying that emerges in connections.

Interactionism, otherwise called emblematic connection, is one of the primary points of view in humanism. Interactionism utilizes a miniaturized scale level methodology, concentrating on social connection in explicit circumstances.

dsp73

Answer:

Encounter Hypothesis

Explanation:

The encounter hypothesis is one of the oldest theories that contributed to the understanding of the solar system and the planets.

This hypothesis says that a collision took place as a result of which a large amount of gas was released from the sun which was migrating more towards the same directions around the sun.

The sun eventually passed through a large, dense and thick interstellar cloud and it later appeared in the form of a gaseous envelope. This later gave rise to the creation of planets and finally formed the solar system. This entire formation of planets and the solar system took a huge amount of time.

This can be considered as an alternative to the nebular theory.
