“Is there a significant difference between the resiliency of male and female students?” is an example of ______ question.
a.
Inferential
b.
Associational
c.
Descriptive
d.
Correlational

The statement that is not true is option c. The median is not equal to the range.

The median is the middle value in a dataset when the values are arranged in ascending or descending order. It is less affected by extreme values than the mean, which makes it a better measure of central tendency in skewed distributions.

The median may or may not be equal to the mode in bell-shaped distributions. In some cases, the mode is not well-defined, and in other cases, there may be multiple modes.

The range is the difference between the maximum and minimum values in a dataset and is not related to the median. Therefore, option c is incorrect.

C. Class marks

The horizontal axis of a histogram shows the class marks, which are the midpoints of the data ranges. The vertical axis shows the frequency, or number of data values, in each class.

If mean > median > mode, the distribution is said to be
a.
negatively skewed
b.
symmetric
c.
normal
d.
positively skewed

 

[mqn7gYwM8p]

C. It is equal to the range

 

[🤖]

The correct answer is a. negatively skewed.

In a negatively skewed distribution, the mean is greater than the median which is greater than the mode. This indicates that there are more scores on the higher end of the distribution that pull the mean to the right, while the median is not as affected by extreme scores. The mode is the point where the distribution is the highest, and in a negatively skewed distribution, it is located on the left side of the distribution. This type of distribution is also referred to as a "left-skewed" distribution.

which of the following statement is associated with the symbol for Ha?
a.
is different from
b.
at least
c.
is equal to
d.
is exactly the same as

 

[🤖]

None of the statements is associated with the symbol for Ha.

Ha is actually the alternative hypothesis in statistics, which is typically written as Ha: μ > μ0 (for a one-tailed test where we are testing if the population mean is greater than a specified value μ0) or Ha: μ ≠ μ0 (for a two-tailed test where we are testing if the population mean is different from a specified value μ0).

To find the range of a set, we need to subtract the smallest value from the largest value.

For Set A, the smallest value is 1 and the largest value is 5. So, the range of Set A is 5-1 = 4.

For Set B, the smallest value is 6 and the largest value is 10. So, the range of Set B is 10-6 = 4.

For Set C, the smallest value is 11 and the largest value is 15. So, the range of Set C is 15-11 = 4.

Therefore, the range of all three sets A, B, and C are equal. So, the correct option is c. The range of Sets A, B, and C are equal.
