what are the conditions to obtain internally valid causal estimates from a randomized evaluation?*

Answers

Internal validity examines if the planning, carrying out, and analysis of the study yield objective solutions to the research objectives.

What is internal validity?

Internal validity is defined as the level of assurance that the causal link you are evaluating is not affected by additional variables or circumstances. As a result of ignoring confounding factors, high internal validity enables the researcher to select one explanation over another with sufficient confidence.

When three conditions are met the "cause" precedes the "effect" in time, the "cause" and the "effect" tend to occur together, and a valid causal inference may be drawn. There aren't any logical alternatives to the observed covariation.

Thus, internal validity tests whether the study's planning, execution, and analysis provide unbiased answers to the research objectives.

About what % of the area under the curve of the standard normal distribution is between z = − 2.124 and z = 2.124 (or within 2.124 standard deviations of the mean). Round your percentage to 2 decimal places.

Answers

About 96.63% of the area under the curve of the standard normal distribution is between z = − 2.124 and z = 2.124 (or within 2.124 standard deviations of the mean).

What is the standard normal distribution?

A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution in statistics. Graphs make it simple to identify the following key traits of normal distributions: The mode, median, and mean are all equal. About the mean, the distribution is symmetric; half of the values are below and half are above the mean. Two numbers, the mean and the standard deviation, can be used to describe the distribution.

In statistics, a normal distribution or a Gaussian distribution is a continuous probability distribution for a real-valued random variable. Using graphs, it is simple to spot the following essential characteristics of normal distributions: The mean, median, and mode all have the same values. The distribution is symmetric with respect to the mean; half of the values are below and half are above the mean. The distribution can be described using two numbers: the mean and the standard deviation.

Normal distribution with mean 3.8 and standard deviation 0.4 Sample size 16. What is the standard deviation of the sampling distribution of the sample mean length?

Answers

The standard deviation of the sampling distribution of the sample mean length is of:

s = 0.1.

How to obtain the standard deviation of the sample mean?

According to the Central Limit Theorem, the sampling distribution of sample means of size n, from a normally distributed population in which the mean and the standard deviation are known, has these following features:

Shape: Approximately Normal.Mean: Same as population mean.Standard deviation: standard deviation of the population divided by the sample size.

In the context of this problem, the values of the parameters are given as follows:

Standard deviation of the population: 0.4.Sample size: 16.

The square root of the sample size is of:

4.

Hence the standard deviation of the sampling distribution of the sample mean length is of:

0.4/4 = 0.1.
