Averages from a table KO quiz

The median is...

• The number that occurs the most often.

• The middle number, when the numbers are in size order.

• The difference between the biggest value and smallest value.

• The total of all the numbers divided by how many numbers there are.

The mode is...

• The number that occurs the most often.

• The middle number, when the numbers are in size order.

• The difference between the biggest value and smallest value.

• The total of all the numbers divided by how many numbers there are.

The mean is...

• The number that occurs the most often.

• The middle number, when the numbers are in size order.

• The difference between the biggest value and smallest value.

• The total of all the numbers divided by how many numbers there are.

The range is...

• The number that occurs the most often.

• The middle number, when the numbers are in size order.

• The difference between the biggest value and smallest value.

• The total of all the numbers divided by how many numbers there are.

To find the mode in a frequency table you need to...

• Find the number which has the highest frequency.

• Find the largest number in the table.

• Find the largest number in the category column (first column).

• Find the number that appears in the table more than the others.

To find the range in a frequency table you need to...

• Take the smallest number away from the largest number.

• Take away the smallest frequency from the largest frequency.

• Take the smallest category number from the largest category number.

• Take the smallest category number (that has some frequency) from the largest category number (with some frequency)

To find the mean from a frequency table you need to...

• Add up all the frequencies and divide by the number of categories.

• multiply the category number by the frequency, add them up and divide by the number of categories.

• multiply the category number by the frequency, add them up and divide by the total frequency.

• add up all the numbers in the table and divide by how many numbers there are.

To find the median from a frequency table you need to...

• Total frequency +1 then divide by 2.

• Total frequency +1 then divide by 2. To find the middle value. Then find the group with this value in

• Find the middle category. If there are two categories in the middle, add them together and divide by 2.

• Write the frequencies in order and find the middle value. If there are two of them add them up and divide by 2.
