Question

Mean, Medlan, Mode, and Range HINTS: (Make sure you ALWAYS order from L→ G Mean (average) - Getting frustrated. Requires the most work. (+ and then +) Previous Median - Finding the MIDDLE #. If there's 2 middle #'s, then find the MEAN of those 2 #'s. > Skip Mode - Most Often (which #occurs the MOST often) Range - Think of golf range. Starting point to ending point. (Greatest Value - Least Value) Suban The number of cups of coffee sold at a coffee vending machine outlet in a busy street for 5 days are listed below. Calculate the MMMR. {6, 11, 10, 17, 14, 11, 17, 10) Mode: Mean: Range: Median:

Answer 1

Mean: to find the mean you add all the data and then divide into the number of data.

number of data: 8

$\frac{6+11+10+17+14+11+17+10}{8}=\frac{96}{8}=12$

Mean: 12

Median: to find the meadian order the data from least to greather and then select the middle data (as the total of data is 8 you select the two data in the middle and calculate the average)

Data ordered:

$6,10,10,11,11,14,17,17$

Middle data: 11 and 11:

$\frac{11+11}{2}=11$Median: 11

Mode: To find the mode you look for the data that repeat the most.

Mode: As the number 10, 11 and 17 repeats all 2 times. There data set is trimodal: Mode: 10, 11 and 1711 and 17

Range: To find the range of a data set you substract from the greatest value the least value:

Greatest value: 17

Least value: 6

$17-6=11$Range: 11
