Answer:
Range:the largest number in the sequence minus the lowest number in the sequence
Median:the middle number in the sequence when the numbers are in order from least to greatest or vise vearsa if there are two middle numbers then you add them together and divide the answer by two
Mode:the number that appears most often in the sequence
Mean:also known as the average you add all the numbers together then divide the answer by the number of numbers you added together
Example:
1,4,66,7,8,40,93,3,4,4
Range: 92 (93-1=92)
Median:5.5 (1,3,4,4,4,7,8,40,66,93)(4+7=11)(11/2=5.5)
Mode:4
Mean:23 (1+3+4+4+4+7+8+40+66+93=230)(230/10=23)
