30. ___________ consists of numbers representing counts or measurements.

Mathematical data

Categorical data

Quantitative data

Population data

Answer: Quantitative data

Are the data non-normally distributed?

Answer: Watch for mistakes in data entry and extreme values (outliers) Visual inspection of the distribution data will help identify Examination of the skew and kurtosis Inferential tests of normality (e.g., Kolmorogov-Smirnov) with help identify Best to combine visual inspection and objective tests to evaluate normality **Blind the administrator to try and avoid this

What could the outliers be from?

Answer: N/A

Unimodal

Answer: Several average scores and fewer high and low scores on either side of the mean

Bell shaped curve

Bimodal

Answer: Scores accumulate at two different parts of the scale (two different modes)

Skewed

Answer: Scores are mainly high or low They are not normally distributed Not symmetrical Can be positive or negative -We don’t want this because it means that there are outliers. *Image is positively skewed

Normal Distribution

Answer: Provides a model for real-life variables Used for determining the probability of certain outcomes Is unimodal (one mode in the center) Is symmetrical Is continuous Is asymptotic (i.e., gets closer to the horizonal axis as it moves away from the center but never touches the axis) 68% will be within 1 standard deviation (e.g., average range) 95% will fall within 2 standard deviations 99% will fall within 3 standard deviations

What is the definition of an infinite number of values between two points:

a) Continuous Variables b) Discrete Variables c) Dichotomous Variables

Answer: a) Continuous Variables

What is the definition of a finite value between two points:

(ex: Number if children, can’t have half a child) a) Continuous Variables b) Discrete Variables c) Dichotomous Variables

Answer: b) Discrete Variables

What is the definition of a measurement that only has two value choices?

(Male/Female): a) Continuous Variables b) Discrete Variables c) Dichotomous Variables

Answer: c) Dichotomous Variables

What are the four levels of measurement?

Answer: 1. Nominal 2. Ordinal 3. Interval 4. Ratio
