How do you calculate the mean of a data set?

• Multiply all values and divide by the number of values

• Add all values and divide by the number of values

• Subtract the smallest value from the largest value

• Count the number of values and divide by two

What is an outlier in the context of data analysis?

• The most common value in a data set

• A value significantly higher or lower than other values

• The average value of a data set

• The middle value in an ordered data set

How does an outlier affect the calculation of the mean?

• It can significantly increase or decrease the mean

• It does not affect the mean

• It eliminates other values from consideration

• It changes the order of data

What is the correct way to handle outliers when calculating the mean?

• Outliers do not influence the calculation of the mean

• Outliers should be multiplied by two before calculation

• Include outliers and adjust the mean accordingly

• Ignore all outliers and calculate with remaining data

What is the median of a data set?

• The sum of all values divided by the number of values

• The middle value when data is ordered

• The most frequent value

• The average of all values

How is the median calculated when there is an even number of data points?

• It is the average of the two middle values

• It is the sum of all values divided by two

• It is the value exactly at one-quarter of the data set

• It is the value at the first position

What does the mode represent in a data set?

• The value exactly in the middle of the dataset

• The difference between the highest and lowest values

• The value that appears most frequently

• The least occurring value

Can you find a mode in a data set of favorite colors?

• No, because all colors are equally common

• Yes, it is the color mentioned most often

• No, because colors are not numerical values

• Yes, it is the average color
