Calculating Mode, Median, Mean, Range, and Standard Deviation

What are the measures of central tendency discussed?

• Mode, Median, Mean, Range, Standard Deviation

• Histograms, Stem Plots, Pie Charts

• Variance, Standard Deviation

• Range, Variance

How is the mode of a dataset defined?

• The average of all data points

• The middle value of the dataset

• The most frequently occurring data value

• The difference between the highest and lowest values

What formula is used to find the position of the median in an ordered dataset?

• 2n

• n-1

• (n+1)/2

• n/2

What is the significance of the formula (n+1)/2 for finding the median?

• It determines the mode

• It calculates the mean

• It helps locate the median's position in an ordered dataset

• It is used when the dataset has an even number of values

How do you calculate the mean of a dataset?

• Sum of all data values divided by the number of values

• The most frequently occurring value

• The maximum value minus the minimum value

• The middle value of an ordered dataset

How does the median differ from the mean?

• The mean is the middle value, while the median is the average

• There is no difference

• The median is the middle value, while the mean is the average

• The median is always higher

What does the range of a dataset tell us?

• The middle value of the dataset

• How spread out the data is

• The average value of the dataset

• The most common value

How is standard deviation calculated?

• Maximum value minus minimum value

• Difference between the mean and median

• Average of squared differences from the mean

• Sum of all data values

What does a small standard deviation indicate?

• Low variability in the dataset

• High variability in the dataset

• The dataset is not spread out

• Both B and C

What is variance?

• The square root of the standard deviation

• The average of the dataset

• The squared standard deviation

• None of the above
