Frequency Distributions
Define the term Frequency Distributions?
Expert
A frequently distribution ( frequency table ) records the number of times each value occurs (frequency).
Grouped Frequency:
The size of each class should be appropriateThe upper and lower limit should be suitable
Cumulative:
To show the total number of items that a value above or below a certain amount occurs.
Grouped Frequency Distributions: Guidelines for classes: A) There must be between 5 to 20 classes. B) The class width must be an odd number. This will assure that the class mid-points are integers rather than decimals. C) The classes should be mutually exclusive. This signifies that no data valu
Activity 10: MANOVA and Reflection 4Comparison of Multiple Outcome Variables This activity introduces you to a very common technique - MANOVA. MANOVA is simply an extension of an ANOVA and allows for the comparison of multiple outcome variables (again, a very common situation in research a
Question 1 Do parents with more children travel more than parents of small families? To find out, a survey was done of a large number of adults. Respondents were asked how many children they had and how many times
Explain sampling bias and describe how random sampling serves to avoid bias in the process of data collection.
Suppose we have a stick of length L. We break it once at some point X _ Q : Problem on Chebyshevs theorem 1. Prove 1. Prove that the law of iterated expectations for continuous random variables.2. Prove that the bounds in Chebyshev's theorem cannot be improved upon. I.e., provide a distribution which satisfies the bounds exactly for k ≥1, show that it satisfies the

Consider a consumer with probability p of becoming sick. Let Is be the consumer’s income if he becomes sick, and let Ins be his income if he does not become sick, with Is < Ins. Suppo
The design of instrument controls affects how easily people can use them. An investigator used 25 students who were right-handed to determine whether right-handed subjects preferred right-handed threaded knobs. He had two machines that differed only in that one had a
1) Construct a 99% confidence interval for the population mean µ. 2) At what significance level do the data provide good evidence that the average body temperature is
A) What is the probability of getting the following sequence with a fair die (as in dice):B) What is the probability of getting the same sequence with a die that is biased in the following way: p(1)=p(2)=p(3)=p(4)=15%;
