    Please, what is the dependent and independent variable for this research topic “knowledge and determinants of substance use and abuse among people living with special needs in ibadan.
    Hope to hear from you soon. Thank you for reply in advance

  6. Andale

    The independent variable is constant (i.e. it doesn’t change) so I would say the people living with special needs is the independent variable. So substance abuse would be the dependent.

    Hi, I’m applying for a post as an Assistant Statistician in Northern Ireland. Part of that application involves being tested on “basic statistical and social research concepts”. It’s been 6 years since I graduated with a Psychology degree ans (sadly) most of my statistics knowledge has evaporated. Is there a resource on this site that might prove helpful?

    Thanks in advance

    Hi. I intend to do my undergrad research on Occupational Safety and Health among farm workers, focusing on factors affecting safety and health practices on the farm. Could you give me some pointers on the study design, variables, and data analysis methods?

    I’m stupid with this statistics. Here is the problem. Past records indicate that the probability of online retail orders that turn out to be fraudulent is 0.08. suppose that, on a given day, 20 online retail orders are placed. Assume that the number of online retail orders that turn out to be fraudulent is distributed as a binomial random variable. (a) what are the mean and standard deviation of the number of online retail orders that turn out to be fraudulent? (b) what is the probability that one online retail order will turn out to be fraudulent? (c)what is the probability that one online retail order will turn out to be fraudulent?
    (d) What is the probability that two or more online retail orders will turn out to be fraudulent?

  10. Andale

    Yes, that’s not a problem at all. Please link back to this site. Thanks, and good luck with your project!

    It’s nearly impossible to find well-informed people for this
    subject, but you sound like you know what you’re talking about!

    Can you recommend a good book to learn from before signing up for a class ? Trying to get a head start

    Just wanted to drop a line and say thanks! Came across this site from a google search working on a take-home stats midterm (PhD student). Then came across it again later while working on another problem. Both times it was the MOST helpful site. Awesome site! Much appreciated!

    HI, in the article, “Sampling With Replacement / Sampling Without Replacement”, there is an error. Under sampling without replacement, the outcome “John,John” is listed as a possibility. Since sampling is without replacement and there is only one instance of “John” in the hat. it is impossible for “John” to be drawn more than once.
