Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
![### Understanding Levels of Measurement
**Multiple-Choice Question:**
Movie ratings of one star, two stars, three stars, or four stars is an example of a(n) ______________ level measurement.
- [ ] Ordinal
- [ ] Nominal
- [ ] Interval
- [ ] Ratio
**Explanation:**
In statistics, different levels of measurement are used to categorize and interpret data. The four levels of measurement are nominal, ordinal, interval, and ratio.
1. **Nominal Level**: This is the most basic level of measurement, where data is categorized without a specific order. For example, gender or race are nominal variables.
2. **Ordinal Level**: At this level, data is categorized in a specific order, but the intervals between the values are not necessarily equal. Movie ratings of one star, two stars, three stars, or four stars fall into this category. The ratings imply an order (i.e., four stars is better than one star), but the difference between each rating is not precisely measurable.
3. **Interval Level**: Data at this level have meaningful intervals between measurements, but there is no true zero point. An example is temperature in Celsius or Fahrenheit.
4. **Ratio Level**: This level of measurement has all the features of the interval level, with the addition of a true zero point. Examples include height, weight, and age.
Movie ratings represent an **ordinal level** of measurement because they show an order of preference without defining the precise intervals between ratings.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcfef55d1-e74e-4acc-a65e-b6e34bf1c85d%2F5562d4af-303b-40e4-adf9-1b0a14fd805d%2F42tjzvo_processed.jpeg&w=3840&q=75)
