The statement that a person who scores has twice as much of the trait being measured as someone who scores 60 is appropriate for:. It is not possible to report the average score for data measured on what type of scale? Here is a set of scores: 3,6,2,9,4,7,5,7,7,5. If the scores were entered into a frequency table, what would be the cumulative frequency? Your data consist of the average family size for all families within each of six different income levels.
What type of visual display would best convey the data? Statistics paper help are constructing a histogram for scores that range from 70 to in whole points. Frequencies range from statistics paper help to 10; that is, every whole-point score between 60 and occurs at least 3 times, and at least one score occurs 10 times.
Which of these would probably be the best range and size for the score intervals along the X-axis? You are looking at a frequency table for a large number of scores. Without doing any further calculating, which measure of central tendency can you immediately report?
In a set of raw scores for a teacher-constructed test, what will be the shape of the distribution around statistics paper help mean?
You select a sample of 50 scores from a population of 2, scores. You compute the range and standard deviation on the sample of 50 scores. You then select another sample of 50 scores from the same population. What measure of dispersion is likely to vary most between your first and second samples? Here is a set of scores: 5, statistics paper help, 5, 8, statistics paper help, 14, 22, If the set of scores is changed statistics paper help 6, statistics paper help, 6, 8, 14, statistics paper help, 21, 21, how will these changes affect the standard deviation?
The probability of rolling a 3 on a die is. What is the probability of rolling a 3 on a single roll? The probability of drawing a heart from a deck of cards is.
What is the probability of getting a heart on a single draw? A market researcher obtains a list of all streets in a town.

Statistics paper help an experiment to determine the effect of exercise on weight-loss among postmenopausal women who are employed outside the home, what is the DEPENDENT variable?
A researcher plans to conduct a one-tailed test of her hypothesis at the. Just before running the experiment, statistics paper help, she decides that a two-tailed test is more appropriate. If she does not adjust the error level, how much error will her new study permit in a single tail? Professor Stringent conducts his study at a, statistics paper help. Professor Lax conducts his study at a.
Whose study is the better study? The probability of a score falling at or below a particular z score is. If you reject the null hypothesis, what is your Type 1 error level? What is the probability of a Statistics paper help 1 error if you reject the null hypothesis based on a z score of.
Assume that a population of scores is normally distributed with a mean of 50 and a standard deviation of A population has a mean of and a standard deviation of You draw a random sample from that population.
If the population mean is 50 and the standard deviation is 5, what is the normal deviate Z for a sample of 20 people with a mean of 46? A two-tailed t statistics paper help study for a single sample of 28 participants yields a t of Look up this value in a t-table.
Given the fixed number of participants, what is the lowest tabled alpha level at which this t is statistically significant? In a one-sample t test, if the observed sample mean turns out to be one that would rarely occur when the null hypothesis is true, what should the researcher statistics paper help The square root of the combined sample size of the two samples in the study.
It depends on the value of the raw scores in the two sampling distributions. For a very small sample size, you should expect the size of the standard error of the difference between the means to be:. In a two-sample t test, if the observed difference between the sample means turns out to be one that could easily occur when the null hypothesis is true, what should we do? Repeat the test until we get a less statistics paper help difference between the means.

The appropriate statistic to use when testing the hypothesis for a study with three treatment groups is a:. You have conducted an analysis of variance and found no statistical significance in the F. Should you then calculate a post hoc test? Yes, to locate the confounding variables that might have masked the effect. No, because there is there is no statistical significance to be found, statistics paper help.
You conduct an ANOVA at the. You conduct a Tukey HSD post hoc test on the same data at the same. From these results, you know that:. the sample size in each group statistics paper help not sufficient to pick up the effect detected by the F test. the variation within each group masked the variation between the groups, statistics paper help. you have made a calculation error in either the F test or the Tukey HSD. Your chi-square study has 4 categories or conditions of the first variable and 4 levels or conditions of the second variable.

if the independent variable causes an outcome in the statistics paper help variable.

What would be the predicted score on variable Y for a person who scores 40 on variable X? Note: This can be answered without any formulas or calculations. You conduct a study with four uncorrelated predictors, statistics paper help.
Then you remove one of the predictors, statistics paper help. How should the removal of this predictor change the R2?
