Math 6 - Median and Mode

Mean, Median, and Mode are all...

• Measures of Center.

• Measures of Variation.

What is the median of the data set? 1, 3, 2, 4, 5

• 3

• 2

To find the median, you must...

• order the data least to greatest then find the middle number.

• just find the middle number of data in any old order.

• find the number that comes up "most".

• find the average and hold on for dear life.

Find the mode of the data set: 1, 1, 2, 2, 3, 3

• All numbers come up twice, there's no mode.

• The modes are 1, 2, and 3.

Find the mode of the data set: 1, 1, 2, 2, 3

• All numbers come up twice, there's no mode.

• The modes are 1, 2 because they come up twice but 3 just comes up once.

True or false: there can be no mode, one mode, or many modes.

• True.

• False.

When finding the median...

• students often forget to put the data in order from least to greatest.

• students often find the mean instead.

• students forget to divide by 2.

What are the three measures of center?

• Mean, median, and mode.

• Range, IQR, and MAD.

Mean, median, and mode are the...

• three measures of center.

• three measures of variation.

The mean is found by...

• finding the sum of the data and dividing by the number of data in the data set.

• finding the difference of the data and dividing by the number of data in the data set.

• finding the product of the data and dividing by the number of data in the data set.

• finding the quotient of the data and dividing by the number of data in the data set.
