Answer:

1. Mean

[tex] mean = \frac{(68 + 83 + 79 + 94 + 78 + 84)}{6} \\ = 81[/tex]

2. Median

[tex]in \: ascending \: order \\ 68 \: \: 78 \: \: 79 \: \: 83 \: \: 84 \: \: 94 \\ median = ( \frac{n}{2} + 1) {}^{th} \\ = ( \frac{6}{2} + 1) {}^{th} \\ = 4 {}^{th } value \\ median = 83[/tex]

3. Mode

All the values are repeated once hence mode is none.

4. Range

[tex]range = 94 - 78 \\ = 16[/tex]

Answer:

  1. Mean = 81
  2. Median = 81
  3. Mode =
  4. Range = 26

Step-by-step explanation:

Mean: the total of all the numbers, divided by the amount of numbers.

[tex]\frac{68+83+79+94+78+84}{6}[/tex] = [tex]\frac{486}{6}[/tex] = 81

Median: the middle value when numbers are in order.

68, 78, 79, 83, 84, 94 [tex]\frac{79+83}{2}[/tex] = 81

Mode: The value which is written the most.

There isn't one.

Range: the largest number minus the smallest number.

94 - 68 = 26
