1. Z-score is special, because it STANDARDIZES the results

True

False

The given statement is true. Z-score is a statistical measurement that standardizes the results by converting them into a standard normal distribution. It allows for the comparison of data points from different normal distributions, making it easier to analyze and interpret the data. By standardizing the results, the Z-score enables researchers to determine how far away a particular data point is from the mean, in terms of standard deviations. This standardization is useful in various fields, such as finance, psychology, and education, where comparisons and interpretations of data are necessary.

2. Most scenerios for Z scores

True

False

The statement "Most scenarios for Z scores are true" is correct. Z scores are a statistical measure that represents how many standard deviations an individual data point is from the mean of a data set. Z scores can be used to compare different data points from different distributions. In most scenarios, Z scores are used to standardize data and make comparisons easier. Therefore, the statement is true.

Explanation

3. The three rules of the MEAN are: 1: All #- mean then sum= 0, 2) is exact middle on bell curve, 3) most values are close to it

True

False

The statement is true because the three rules of the MEAN are accurately described. The first rule states that if all the values in a data set are subtracted by the mean and then summed, the result will be zero. The second rule states that the mean is the exact middle point on a bell curve, also known as the normal distribution. The third rule states that most values in a data set are close to the mean. Therefore, the given statement accurately represents the three rules of the MEAN.

Explanation

4. Standard deviation

Step 1: substract the #s - the Mean

Step 2: Take answers and SQUARE them

3) Add all the values

step 4: Divide by n or N

Step 5: Square root the #

The given answer provides the correct steps to calculate the standard deviation. Step 1 involves subtracting the numbers from the mean. Step 2 requires squaring each of the answers obtained in the previous step. Step 3 involves adding all the squared values together. Step 4 requires dividing the sum by the total number of values (n or N). Finally, step 5 involves taking the square root of the obtained result. This sequence of steps accurately describes the process of calculating the standard deviation.
