Home>Mathematics homework help>Statistics homework help This week covers probability and non-probability sampling. Discuss in detail the characteristics of probability and nonprobability sampling. Discuss the reasons that researchers would use conditional probability instead of unconditional probability in their study. Be sure to support your statements with logic and argument, use at least two peer reviewed articles […]

 run new descriptive statistics for Recall1 using Microsoft Excel. Assuming that the sample statistics you computed are exactly equivalent to the corresponding population parameters, and using the formula X = (±z)(sd) + M (see below) identify the following: The exact score on Recall1 that would fall at the upper 5% cutoff (extremely high score?) (Be […]

 Reply to One variable, x, is known as the predictor variable. The other variable, y, is known as the criterion variable, or response variable. In a simple linear regression, we find a “line of best fit” that describes the relationship between the predictor variable and the criterion variable. This process is so useful in studies […]

 Reply to According to (Gravetter et al, 2021) a criterion variable is another name for a response variable or a dependent variable. The criterion variable is the variable that is being predicted in statistical analysis. A statistical method that is used to understand the relationship between two variables x and y is also known as […]

 Reply to A predictor variable, not to be confused through its similarities with independent variable, is used in efforts to predict an outcome. The difference comes from the predictor variables not being manipulated by the researcher, but rather naturally occurring changes. In other words, this would be looking at a variable as it naturally happens […]

Reply to  Explain what is meant by a positive relationship between two variables and a negative relationship between two variables. Describe examples of situations in which one would expect to find a positive relationship and when one would expect to find a negative relationship. Can one assign direction when both variables in a table are […]

Home>Mathematics homework help>Statistics homework help You had the chance earlier in the course to practice with multiple regression and obtain peer feedback. Now, it is time once again to put all of that good practice to use and answer a social research question with multiple regression. As you begin the Assignment, be sure and pay […]

 To prepare for this Assignment, imagine that you have information about how 20 nursing students and 20 psychology students felt about starting PSYC 3002 on Day 1 of this class. You want to know if nursing students and psychology students felt differently about embarking on the Introduction to Basic Statistics journey.     9 Nervous Nursing […]
