The number of dry cleaning orders picked up at Sunny Fresh Dry Cleaners was sampled over 12 hour periods. Below is the sample: 142 171 125 91 140 125 97 125 162 142 125 117 89 125 140 128 From this data set, compute the sample mean, median, mode and midrange. Compute the 1st quartile and 3rd and interpret their meanings
mean is another name for average: add up the samples and divide by the number of samples
the median is the middle number. if you have an even number, the median is the average of the 2 middle numbers. mod is the most common number.
what is midrange mean?
i got 127.5 for mean,median 125,mode 125. can you helpme with the midrange and th second part interpret there meanings
midrange is the average of largest and smallest number
so i get 89 and 171add the two thn divede tm by tand get the average that would be 89+171=230 divided by 2 equals 130 is that right
ya
what about the last part intrepret their meanings
1st iq is the median of lower set and 3rd iq is median of upper set
so it gives you the length of the box plot
confused
the first quartile is the 25th percentile and 3rd quartile is the 75th percentile
