What is a sample in the context of statistics?

• A single measurement

• The entire population

• A collection of measurements

• The average of measurements

What is the role of standard deviation in statistics?

• To measure the spread of data points

• To calculate the average

• To find the median

• To determine the mode

What is the significance of discussing sample statistics?

• It helps in understanding the sample's deviation from the population

• It eliminates the need for further data collection

• It provides the exact value of the population

What is the standard uncertainty used to describe?

• The range for individual measurements

• The range for the average

• The total number of measurements

• The highest measurement value

How is the standard uncertainty defined?

• Δx = s/N

• Δx = s/√N

• Δx = s/N-1

• Δx = s/√(N-1)

What is the role of the standard deviation in characterizing data?

• It records the average value

• It records how widely data are spread

• It records the total number of measurements

• It records the highest value
