Performance Task

2. Is a measure of spread of the probability distribution.
4. It is a descriptive population measure.
8. It has a countable number of possible values.
13. It measures the strength of the linear relationship between two variables.
14. It is the number that describes the sample.
15. Is a similar to a normal distribution.
16. It can assume an infinite number of values in one or more intervals.
17. Is a continuous probability distribution that is symmetrical around its mean with most values near the central peak.
19. Is a sampling technique in which members of the population are listed and samples are selected at intervals called sample intervals.

1. It is a measure degree of accuracy of the sample mean as an estimate of the population mean.
3. States that the sampling distribution of the mean approaches a normal distribution, as the sample size increases.
4. Is a measure used in statistics indicating the value below which a given percentage of observation in a group of observation fall.
5. Result of chance event, that you can measure or count.
6. It referred to as the three-sigma rule or 68-95-99.7 rule.
7. The state of not being correlated or connected.
9. The average of the squared deviations of the random variable from its mean (expected value).
10. Is a sampling technique in which each member of the population has an equal chance of being selected.
11. The central value or average of a corresponding probability mass function.
12. Are the graphs that present the relationship between two variables in a data set.
18. Is a subset taken from a population, either by random sampling or by non-random sampling.
