What is the definition of median?

• The median is the middle value in a set of numbers.

• The median is the lowest value in a set of numbers.

• The median is the highest value in a set of numbers.

• The median is the average of all the numbers in a set.

What is the definition of mode?

• The mode is the median value in a dataset.

• The mode is the value that appears least frequently in a dataset.

• The mode is the average of all the values in a dataset.

• The mode is the value that appears most frequently in a dataset.

What is the definition of range?

• The range is the middle value in a set of data.

• The range is the average of all the values in a set of data.

• The range is the sum of all the values in a set of data.

• The range is the difference between the highest and lowest values in a set of data.

What is the definition of outlier?

• A data point that is significantly different from other similar data points in a dataset.

• A data point that is the average of all data points in a dataset

• A data point that is similar to other data points in a dataset

• A data point that is not included in the dataset

What is the definition of a parameter?

• A parameter is a numerical value that describes a sample.
• A parameter is a qualitative characteristic of a population.
• A parameter is a numerical value that describes a population.
• A parameter is a statistical measure used to analyze data.

What is the definition of a sampling in statistics

• Sampling is the process of selecting a single individual from a population to gather information about the whole population.
• Sampling is the process of selecting a subset from a smaller population to gather information about the whole population.
• Sampling is the process of selecting a subset from a larger population to gather information about the whole population.
• Sampling is the process of selecting a subset from a larger population to gather information about a specific group within the population.

What is a histogram?

• A way of displaying one-variable data that is like a bar graph in that the height of the bars is proportional to the number of elements.  However, a histogram is for numerical data

• A hidden variable that was not part of the statistical study under investigation.  Sometimes a lurking variable explains the true cause of an association between two other variables that are linke

• A distribution of data that can be modeled with the normal probability density function

What is a lurking variable in a observational survey?

• A way of displaying one-variable data that is like a bar graph in that the height of the bars is proportional to the number of elements.  However, a histogram is for numerical data.

• A hidden variable that was not part of the statistical study under investigation.  Sometimes a lurking variable explains the true cause of an association between two other variables that are linked

• A distribution of data that can be modeled with the normal probability density function.

• A funny ghost or goblin.

What is the definition of standard deviation?

• Standard deviation measures the central tendency of a set of values.

• Standard deviation is the average of a set of values.

• Standard deviation is a measure of the spread between the highest and lowest values in a set.

• Standard deviation is a measure of the amount of variation or dispersion in a set of values.
