Find the median of $3,\ 8,\ 5,\ 1,\ 9$.

1ordered: $1,\ 3,\ 5,\ 8,\ 9$Put the values in order (smallest first)

2middle of $5$ values is the $3$rd: median $=5$Take the middle value

Check - Why must we order the list first?

A the median is the middle of the ORDERED dataB to make it look neatC ordering changes the meanD you do not need to order it

Find the median of $7,\ 2,\ 9,\ 4,\ 6$.

1ordered: $2,\ 4,\ 6,\ 7,\ 9$Put the values in order (smallest first)

2middle value $=6$Take the middle value

Check - With $5$ values, which position is the median?

A the $2$ndB the $3$rd (the middle)C the lastD the mean of all

3you finish it

Find the median of $10,\ 4,\ 7,\ 4,\ 1$.

1ordered: $1,\ 4,\ 4,\ 7,\ 10$Put the values in order (smallest first)

2Take the middle value

Check - The number $4$ appears twice. Does that change the median here?

A no – you still take the middle of the ordered listB yes, you remove duplicates firstC the median becomes the modeD you add the two $4$s

4you do it all

Find the median of $6,\ 3,\ 8,\ 5,\ 9,\ 2$.

1Put the values in order (smallest first)

2Take the middle value

Check - There are $6$ values (an even number). What do you do?

A pick either middle valueB take the mean of the two middle valuesC there is no medianD take the larger middle value
