Q: The value of the mean and the median defines if the minimum of data is located right or left
- absolute freq.
- cumulative freq.
- relative freq.
- positive or negative skew
A: positive or negative skew

Q: If the value of the mean is less than the median in a normal distribution, that means that the skew is:
- positive
- symmetrical
- negative
A: negative

Q: Having the following sample of data

1 | -5 | 13 | 4 | -8 | -4 | 5 | 6

calculate the mean, median and mode
- 2.5, 1.5, mode 4
- 1.5, 3, mode 4
- 1.5, 2.5, no mode
- 1.5, 2.5, mode 5
A: 1.5, 2.5, no mode

Q: Find the type of mode included in the following set of data.

58 | 81 | 71 | 45 | 62 | 61 | 92 | 72 | 55 | 60 | 92 | 49 | 55 | 73 | 95 | 72
- one mode
- bimodal
- multimodal
A: multimodal

Q: For the following group of data, 4, 5, 5, 7, 8 and 13, select the true statement:
- There is no mode
- The median is greater than the mean
- The mean is 7
- The mode is greater than the mean
A: The mean is 7

Q: What is the value of the mode?
- 16
- 17
- 32
- 37
A: 17
