• Used with continuous data

Answer 67

• Usually used with ordinal and continuous data

Answer 68

• Affected by extreme values

Answer 69

• More difficult to understand

Answer 70

• Unlikely to be a value in the set

Answer 71

This is normal because the mean, median and mode lies in the same place, the mean is the preferred method.

Answer 72

The mean is dragged in the direction of the skew so the median is the preferred measure (an easy test – ceiling effect).

Answer 73

The mean is dragged in the direction of the skew so the median is the preferred measure (an easy test – ceiling effect).

Answer 74

The mean is dragged in the direction of the skew so the median is the preferred measure (an easy test – ceiling effect).

Answer 75

They are helpful for indicating whether a distribution is skewed and if there any unusual observations (outliers) in the data set.

Answer 76

They are useful when large numbers of observations are involved or comparing two or more data sets.

Answer 77

Line graph

Answer 78

Scatter diagram

Answer 79

Nominal data

Answer 80

Continuous data

Answer 81

Ordinal data

Answer 82

Ratio data

Answer 83

Categorical data

Answer 84

Interval data

Answer 85

When quantities that are ordered y criteria such as positions in a rate. However it does not allow you to state whether the intervals between each value are equal.

Answer 86

categorically discrete data such as the name of your school or the car you drive.

Answer 87

This is like like ordinal data except the intervals between each value is equally split, such as the time of day on a clock.

Answer 88

like ordinal data except the intervals between each value is equally split, such as the time of day on a clock.

Answer 89

interval data with a natural zero point (ruler in cm).

Answer 90

When quantities that are ordered y criteria such as positions in a rate. However it does not allow you to state whether the intervals between each value are equal.

Answer 91

The median could be a measure of central tendency for this.

Answer 92

The median could be a measure of central tendency for this.

Answer 93

this is like ordinal data except the intervals between each value is equally split, such as the time of day on a clock.

Answer 94

this is like ordinal data except the intervals between each value is equally split, such as the time of day on a clock.

Answer 95

interval data with a natural zero point (ruler in cm).

Answer 96

data which is divided into groups (types of animals). This data is nominal and discrete.

Answer 97

The mode would be the measure of central tendency as it cannot be used with arithmetic.

Answer 98

Representations could include a bar chart with gaps between the bars (grouped discrete data)

Answer 99

data restricted to a limited set of discrete values (shoes size and money)

Answer 100

data which can take any value within a range (height). The mean could be a measure of central tendency, this is because it would give you the arithmetic average for the large range of data which can then be used in statistics.

Answer 101

The median could be used if the data was skewed because this would be more representative of the data.

Answer 102

Representations could include a line graph or a histogram (grouped continuous)

Answer 103

data restricted to a limited set of discrete values (shoes size and money)

Answer 104

data which is divided into groups (types of animals). This data is nominal and discrete. The mode would be the measure of central tendency as it cannot be used with arithmetic.
