Construction discussions Working at height Scaffold checklist — A guide for when scaffold design is required and what level of training and competence those erecting, dismantling, altering, inspecting and supervising scaffolding operations are expected to have obtained. Managing work at height follows a hierarchy of controls — avoid, prevent, arrest — which begins with the question — can the work be done safely from the ground? Fall restraints and safety netting should only be considered as a last resort if other safety equipment cannot be used. Multiple Regression Analysis using Stata Introduction Multiple regression an extension of simple linear regression is used to predict the value of a dependent variable also known as an outcome variable based on the value of two or more independent variables also known as predictor variables.

For example, you could use multiple regression to determine if exam anxiety can be predicted based on coursework mark, revision time, lecture attendance and IQ score i. Alternately, you could use multiple regression to determine if income can be predicted based on age, gender and educational level i.

If you have a dichotomous dependent variable you can use a binomial logistic regression. Multiple regression also allows you to determine the overall fit variance explained of the model and the relative contribution of each of the independent variables to the total variance explained.

For example, you might want to know how much of the variation in exam anxiety can be explained by coursework mark, revision time, lecture attendance and IQ score "as a whole", but also the "relative contribution" of each independent variable in explaining the variance. This "quick start" guide shows you how to carry out multiple regression using Stata, as well as how to interpret and report the results from this test. However, before we introduce you to this procedure, you need to understand the different assumptions that your data must meet in order for multiple regression to give you a valid result.

We discuss these assumptions next. Stata Assumptions There are eight "assumptions" that underpin multiple regression. If any of these eight assumptions are not met, you cannot analyze your data using multiple regression because you will not get a valid result.

Since assumptions 1 and 2 relate to your choice of variables, they cannot be tested for using Stata. However, you should decide whether your study meets these assumptions before moving on. Your dependent variable should be measured at the continuous level.

If you are unsure whether your dependent variable is continuous i. You have two or more independent variables, which should be measured at the continuous or categorical level.

For examples of continuous variables, see the bullet above. Examples of categorical variables include gender e. Caucasian, African American and Hispanicphysical activity level e.

In this guide, we show you the multiple regression procedure because we have a mix of continuous and categorical independent variables. If you only have categorical independent variables i.

Fortunately, you can check assumptions 3, 4, 5, 6, 7 and 8 using Stata.

When moving on to assumptions 3, 4, 5, 6, 7 and 8, we suggest testing them in this order because it represents an order where, if a violation to the assumption is not correctable, you will no longer be able to use multiple regression.

In fact, do not be surprised if your data fails one or more of these assumptions since this is fairly typical when working with real-world data rather than textbook examples, which often only show you how to carry out linear regression when everything goes well. Just remember that if you do not check that you data meets these assumptions or you test for them correctly, the results you get when running multiple regression might not be valid.Introduction In this coursework I will be looking at various lines of enquiry based on data collected from Mayfield High School.

Therefore I will be doing an investigation into the relationship between height, weight, body mass index and age of boys and girls at this school.

Weight is due to the gravitational force of attraction between two bodies. It is proportional to the mass of the bodies and inversely proportional to the square of the distance apart. In engineering, this force acting on a structure is known as a load. The Pre-Social Work Associate of Arts degree program provides a broad based two year Associate of Arts (A.A.) degree curriculum.

My teacher advised me to carry out two main tasks within the overall investigation. It was suggested that I carry out one. Three years’ worth of statistics are included for certain types of crimes that were reported to have occurred on campus, in or on off-campus building or property owned or controlled by the university or on public property within or immediately adjacent to the campus.

Notice that hand span is measured in centimeter which is a finer unit of measurement, to account for the fact that a difference in hand span is on a relatively finer scale compared to difference in height, which can be measured in inches (and is typically measured in feet and inches).
