I've just starting learning MIPS. Can anyone please help me with the codes for finding mean, median and mode of an array? TIA.
.data
newline: .asciiz "\n"
total: .asciiz "Sum: "
mean: .asciiz "Mean: "
median: .asciiz "Median: "
mode: .asciiz "Mode: "
array: .word 1, 2, 2, 3, 3, 3, 4, 4, 5, 5
.word 5, 5, 5, 5, 6, 6, 6, 7, 8, 8
.word 8, 8, 8, 8, 8, 9, 9, 9, 10, 10
length: .word 30
sum: .word 0
average: .word 0
.text
