7.
Part of a subgroup of the given population in which every member has an equal chance of being included in the sample.
Correct Answer
A. Random Sample
Explanation
A random sample is a subset of a population in which every member has an equal chance of being included. This means that each individual or item in the population has the same probability of being selected for the sample. Random sampling helps to ensure that the sample is representative of the population and reduces the potential for bias. It allows for generalizations to be made about the entire population based on the characteristics observed in the sample.
8.
A ration scale includes an interval scale with a true 0 point.
Correct Answer
A. True
Explanation
A ration scale includes an interval scale with a true 0 point. This means that the scale not only measures the differences between values but also has a meaningful and absolute zero point. In other words, a value of zero on a ratio scale represents the complete absence of the measured attribute. This allows for meaningful ratio comparisons between different values on the scale.
9.
Sample is a part or subgroup of the given population.
Correct Answer
A. True
Explanation
A sample is indeed a part or subgroup of the given population. When conducting research or surveys, it is often not feasible or practical to collect data from the entire population. Instead, a smaller representative group, known as a sample, is selected to gather information and make inferences about the larger population. This allows researchers to draw conclusions and make generalizations about the population based on the characteristics and behaviors observed within the sample. Therefore, the statement that a sample is a part or subgroup of the given population is true.
10.
Measures that can have any value within a certain range.
Correct Answer
B. Continuous Data
Explanation
Continuous data refers to a measure that can have any value within a certain range. Unlike discrete data, which can only take on specific values, continuous data can take on any value within a given interval. For example, the height of a person or the weight of an object are continuous data because they can have any value within a certain range.
11.
Measures that can have ONLY seperate values?
Correct Answer
A. Discrete Data
Explanation
Discrete data refers to data that can only take on separate, distinct values. It cannot be measured or divided into smaller units. This is in contrast to continuous data, which can take on any value within a certain range. Examples of discrete data include the number of children in a family, the number of cars in a parking lot, or the number of students in a classroom.
12.
Measures not arranged in any meaningful manner?
Correct Answer
D. Ungrouped Data
Explanation
Ungrouped data refers to a set of data that is not organized or arranged in any specific manner. It lacks any grouping or categorization, making it difficult to analyze or draw meaningful conclusions from the data. This type of data is typically presented as individual values or observations, without any grouping into intervals or categories. Therefore, the given correct answer suggests that the measures are not arranged in any meaningful manner, indicating that they represent ungrouped data.
13.
Measures are arranged in some meaningful manner.
Correct Answer
C. Grouped Data
Explanation
Grouped data refers to a way of organizing and presenting data in which the values are grouped into intervals or classes. This is done to simplify the data and make it more manageable for analysis. In grouped data, the values are arranged in a meaningful manner by grouping them into specific ranges or categories. This allows for easier interpretation and analysis of the data, as it provides a clear overview of the distribution and patterns within the data set.
14.
Provides information about the order of variable and uses equal units of measurement.
Correct Answer
B. Interval Scale
Explanation
The interval scale provides information about the order of variables and uses equal units of measurement. This means that the variables can be ranked in a specific order and the difference between any two values is meaningful. However, the scale does not have a true zero point, meaning that ratios cannot be calculated.
15.
Score that represents the exact middle or the 50% of the group.
Correct Answer
B. Median
Explanation
The median is the score that represents the exact middle or the 50% of the group. It is calculated by arranging the scores in order and finding the middle value. If there is an even number of scores, the median is the average of the two middle values. The median is used to measure the central tendency of a set of data and is particularly useful when there are extreme values or outliers that could skew the mean.
16.
It describes the middle characteristics of a distribution of scores.
Correct Answer
D. All of the above
Explanation
The mean is a measure of central tendency that describes the middle characteristics of a distribution of scores. It is calculated by summing up all the values in the distribution and dividing it by the total number of values. The mean is useful in determining the average value of a set of data and can provide insights into the overall trend or typical value within the dataset. Therefore, the mean is the correct answer as it best fits the description provided.
17.
The scores that occur the most?
Correct Answer
A. Mode
Explanation
The mode is the correct answer because it refers to the scores that occur the most frequently in a data set. It is the value that appears most often and can be used to determine the most common or popular score in a given set of data. The mode is particularly useful when dealing with categorical or discrete data, where there may not be a clear numerical range or median value.

B. Measures of variability
Explanation
The correct answer is "Measures of variability." Variability refers to the extent to which data points differ from each other. Measures of variability, such as the standard deviation, provide a way to quantify this spread or scatter in the data. They help us understand how much the values in a dataset deviate from the average or mean value. Therefore, measures of variability are used to assess the degree of diversity or dispersion in a set of data.
20.
Consider the deviation each score is away from the mean of the distribution.
Correct Answer
A. Mean Deviation
Explanation
Mean deviation is a measure of dispersion that considers the deviation of each score from the mean of the distribution. It calculates the average absolute difference between each score and the mean. By taking into account the deviations of all scores, mean deviation provides a comprehensive understanding of the spread of data around the mean. This measure is useful in analyzing the variability of a dataset and comparing the dispersion between different distributions.
