hours | 2 | 3 | 1 | 4 | 5 | 3
find the:
a) mean:

b) median:

c) mode:

d) range:

Explanation:

Step1: List the data values

Data: 2, 3, 1, 4, 5, 3

Step2: Calculate the mean

Sum = 2+3+1+4+5+3 = 18; Mean = $\frac{18}{6}=3$

Step3: Find the median

Sorted data: 1,2,3,3,4,5; Median = $\frac{3+3}{2}=3$

Step4: Identify the mode

Most frequent value: 3

Step5: Compute the range

Range = Max - Min = 5 - 1 = 4

Answer:

a) 3
b) 3
c) 3
d) 4
