Which set of data do you believe to be better? Your data or your friend's data?

Your friends data

Step-by-step explanation:

The rule of statistics is: the more exact the data, the better.

It looks like you just rounded your data to the nearest tenth. This is good, but not nearly as good as rounding it to the nearest hundredth.

This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.

This means that your friend had better data than you.

Hope this helped!

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
