Question 1195521: 2. Suppose that a computer company had the following laptop sales for January 2020: 20,593; 21,150; 23,000; 24,217; 25,500; 20,500; 25,600
24,900; 25,900; 26,500; 26,700; 27,000; 26,500; 24,250
19,500; 24,300; 28,000; 26,500; 59,500
a. Construct a frequency distribution OR boxplot (choose one only) of these daily returns. Show the steps and relevant statistics involved.
b. Calculate the arithmetic mean, median, and mode (if any).
c. Discuss if the data is skewed (specify which way) or symmetric.

order them
19500
20593
20500
21150
23000
24217
24250
24300
24900
25500
25600
25900
26500
26500
26500
26700
27000
28000
59500
Median is 10th of 19 ordered objects. That is 25500.
26500 is the mode (most common, at 3).
mean is 26322 rounded to nearest integer
range is 40000 (largest-smallest)
skewed right because (1) mean is to right of median, and the largest is the furthest from the mean of the 19 items.
box plot
needs Q1, which is the fifth of the first 9 not counting the 10th, and that is 23000
Q3 would be 26500
Draw the box plot with. 23000 low end of box 25500 Q2 and 26500 Q3.
The whiskers are the extremes, 19500 and 59500.
The mean can be an asterisk value in the box plot near Q2.
