When you are asked to find the mode of a data set remember that mode means what shows up most often. Find the mode of the gas prices listed. Here we have some data remember statistics is all about collecting and interpreting real life data what this person did is they went around and looked at a whole bunch of different gas stations and they saw how much gas costs.
There were three stations where gas costs $2.33 a gallon, there were two stations where it costs that, three stations cost that, one station cost that. Mode means what shows up most often. So I’m looking for the most frequent prices.
This is actually what we call a bimodal data set. There are two modes. The two modes are $2.33 and also $2.89, those are my two modes. Sometimes this data might not be presented in a chart like this it might be presented as either a bar graph or a dot graph something like that and you guys will still be able to see that the largest pieces represent these two data prices.
Because mode represents mode means what shows up most often.
