Essay --
Picture the ultimate dream car. Is it a brand new Mustang right off the show room floor? Maybe it is a SUV with heated leather seats. Or it might by something fast and imported, like a Ferrari, Lamborghini, or Porsche. For some people, dream cars don't come from the present or the future, but the past. But getting that dream car from the past isnââ¬â¢t always easy. A lot of the times it is rusting away in some old barn or out in a field with weeds growing through the floorboard. When someone finds that dream car in those conditions they can do a couple different things they can build it into a rat rod. A rat rod is where the outside of the car is left rusty and in the shape it was found in, and has a big powerful motor and a good strong transmission. Or the other choice is to restore the car to its former glory. When someone restore a car to its former glory there are four main categories or steps that they need to do; body work, paint, interior, and engine/transmission. The first step in body work is to take the car apart so that it is easier to get rid of all the dents, paint, and rust. Then take out all of the interior, and take off the mirrors, hood, fenders, and all of the extra parts that will make it easier to get off the paint. Paint stripping methods usually fall into two main categories: abrasive and chemical. In abrasive paint striping there is media blasting, and good old fashion sanding. The way media blasting works is the process of blasting an item with small particles of various abrasive substances at an extremely high velocity in order to remove paint and rust off a vehicle. There are many materials used to media blast cars like walnut shell, plastic beads, baking soda, and different types of sand. D... ...ne have less power. If the original transmission is being used then it as well should be gone through and cleaned. If someone doesnââ¬â¢t want to take the time to take the engine apart and clean every little part and then try to remember where every little piece went then just replacing both the engine and transmission might be the way to go. Buying a brand new engine and transmission has its advantages and its disadvantages. An advantage of buying them new is that they have all new parts and are less likely to break and can take less time than taking apart the engine. A disadvantage is that it can be more expensive than just using the old motor. By completing these steps an old rusted out car can be turned into the ultimate dream car. Whether it is turned in to a rat rod or in to the restored classic car, it is worth all that hard work to get that ultimate dream car.

Realiability and Validity Rosenburg Scale
Reliability and Validity of the Rosenberg Self Esteem Scale Texas A&M University Psychology 203 Introduction The purpose of our study was to evaluate the reliability and validity of the Rosenber Self-Esteem scale scores. Reliability is simply whether the measurement tool you are using measures something consistently. For example does the same test show the same results when administered repeatedly. Validity is the aspect of a measuring tool that signifies its measuring what it says it does.A valid test measures what it says itââ¬â¢s measuring. However you can have a test that is reliable and not valid, for example if a teacher administers a spelling test that the student has to complete on the computer in a five minute time period. A student may get the same score over and over again, indicating itââ¬â¢s reliable, but it may not be valid because what if that student was slow at typing but knew how to spell every word. The test would not be valid because itââ¬â¢s not meas uring just spelling as intended but also typing speed.Both reliability and validity are crucial in and study because if the research instruments are not reliable and valid, then the results of your experiment will always be in question. Method All ninety-nine A&M students (N=99) that participated in the survey were in the same statistical writing course and were required to take the survey as part of the course curriculum. The survey consisted of 24 males and 75 females, with the average age of these participants being around 20 years old, ranging anywhere from 19 to 24 (M=20. 7, SD=. 997). the survey measured self-esteem by using ten items from the Rosenberg Self Esteem Scale. The students were scored by taking the mean of all their responses to the ten questions. 10 different statements that the participant rated on a scale of 1 to 7, (1 being ââ¬Å"disagree strongly â⬠and 7 being ââ¬Å"agree stronglyâ⬠), the higher the score the higher the individuals self-esteem . The scale consisted of 5 revers coded items; an example of a normal item is ââ¬Å"on the whole I am satisfied with myselfâ⬠.A reverse coded item is an opposite statement for example is ââ¬Å"I feel I do not have much to be proud ofâ⬠. Results The 10 item subscale from the Rosenberg Self-Esteem scale appeared to have good internal consistency, (? = . 90). All the survey question appeared to be worth keeping: in fact the deletion of any of the questions would have resulted in a lower alpha score. All 99 participants (N=99) responses to the 10 item survey were averaged together and the self-esteem score for all the participants had ranged from 2. 6-7 with a mean of 5. 4 (M=5. 4, SD=1. 08).The frequency distribution of the average self-esteem scores, illustrated on the histogram, portrays a distribution that is pretty normal but somewhat negatively. This negative distributions means that the participants more frequently had high self-esteem scores than low scores. In fact no participants had a self-esteem score lower than 2. 6. Discussion To ensure that the survey instrument used in this study was actually measuring self-esteem we took a measure of Cronbachs alpha ( or ? ), which is a special measure of reliability known as internal consistency.The internal consistency reliability of survey instruments (e. g. Rosenberg Self-Esteem scale), is a measure of reliability of different survey items intended to measure the same characteristic, in this case self-esteem. For example, there were 10 different questions related to self-esteem level. Each question implies a response scale from 1 to 7. Responses from the group of the 99 respondents have been obtained. In reality, answers to different questions vary for each particular respondent, although the items are intended to measure the same aspect or quantity.The smaller this variability (or stronger the correlation), the greater the internal consistency reliability of this survey instrument. So in this surv ey the self-esteem scale was found to be highly reliable (10 items; = . 90). We can safely assume that our survey items reliably measure self-esteem levels. One other way we might have assessed reliability would have been to get all the participants to take another Self-Esteem survey of similar design but with different questions.In social sciences in particular making sure that your research has construct validity is very important. Construct validity has traditionally been defined as the experimental demonstration that a test is measuring the construct it claims to be measuring, in laymenââ¬â¢s terms; does the measuring tool actually measure the theory under examination.? ââ¬Å"Am I actually measuring what I think I am measuring? In our example construct validity would be how well dos our observational tool (Rosenberg self-esteem scale) assess one dimension of self-esteem.We could of inter-correlated measures of depression with the measures of the revers coded items (SE3,SE5, SE8,SE9,SE10), because depression and the revers coded items have similar underlying constructs. Finally the low correlation between height and self-esteem in our study strengthens our construct validity. I believe it strengthens the overall resolve because common theories of self-esteem have no reliable and valid evidence correlating the two, so we can assume that construct between the two would be low, and if our study showed a strong relationship it would be casue for questions.
