G7-MATH-L3 DATA HANDLING

What does the term 'average' generally represent in data?

• The highest value
• The lowest value
• The central tendency
• The total sum

If Isha studies for an average of 5 hours, what can we infer about her study habits?

• She studies exactly 5 hours every day
• She studies less than 5 hours on some days
• She studies more than 5 hours every day
• Both B and C

Which of the following is NOT a measure of central tendency?

• Mean
• Median
• Mode
• Range

What is the arithmetic mean?

• The most frequently occurring value
• The middle value in a data set
• The sum of all values divided by the number of values
• The highest value in a data set

In what situation would you use the mode as a measure of central tendency?

• When all values are unique
• When you want the average of all values
• When you need the most common value
• When values are in a specific order

What does the median represent in a data set?

• The average of all values
• The value that occurs most frequently
• The middle value when arranged in order
• The highest value

How can a bar graph help in understanding data?

• It shows the exact values only
• It provides a visual representation of frequencies
• It lists all the data points
• It calculates averages

What is a double bar graph used for?

• To show one collection of data
• To compare two collections of data
• To represent data in a pie chart
• To list data in a table

If the average temperature is 40 degrees Celsius, what does this imply?

• It is always 40 degrees
• It is sometimes below or above 40 degrees
• It never changes
• It is the highest temperature recorded

Why might the arithmetic mean not always be the best measure of central tendency?

• It can be affected by extreme values
• It is always the same as the median
• It is difficult to calculate
• It does not represent any data
