What makes an observed score?
The true score and the error score :) A+
What is the raw score of 200 mean and sd of 10?
The raw score is any value that is observed.
Find the z-score that is less than the mean and for which 70 percent of distributions area lies to its right?
It is z = -0.5244
What is one-to-one individual matching?
In the statistical analysis of observational data, propensity score matching (PSM) is also known as one to one individual matching. It is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment.
How do you interpret a negative z- score?
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
Why is climate Alfred wegners evidence?
Alfred Wegener's evidence for continental drift came in the form of similarities in the ancient climates of continents that are now widely separated. Geological evidence, such as matching rock formations and fossil distributions, supported his theory that continents were once connected in a single landmass. Wegener proposed that these continents drifted apart over time, leading to the climate variations observed today.
Are all symmetric distributions normal distributions?
No. There are many other distributions, including discrete ones, that are symmetrical.
What when there in no mode?
Nothing. There are plenty of distributions that have no node (or several).Nothing. There are plenty of distributions that have no node (or several).Nothing. There are plenty of distributions that have no node (or several).Nothing. There are plenty of distributions that have no node (or several).
Are IRA distributions taxable?
It depends on the type of IRA you have. Distributions from a traditional IRA are taxable. Distributions from a Roth IRA are not taxable.
Why normality is required for standard deviation application?
Because the z-score table, which is heavily related to standard deviation, is only applicable to normal distributions.
The binomial and Poisson distributions are examples of discrete probability distributions?
discrete & continuous
Do t distributions have less spread than normal distributions?
I think yes or no
