~Yes, this is a table of information.~

~No, this is a line chart.~

~Yes, the mean is calculated by adding all the values and dividing by the number of values.~

~No, this is the word for the horizontal line along the bottom of a bar or line chart.~

~No, the medium is the number in the middle of a set of data. Half of the numbers are above it and half below it.~
