Consumer printers, esp Ink jet printers are normally very cheap to buy new (the manufacturer takes a loss with profit on the ink). Ive seen a few threads recently about the value of their PC. Z-distribution table. 90% confidence. The significance level, α, is the value that we set as the cutoff point for whether we reject a null hypothesis or not. 0.1% The higher the significance level, the larger the range we have for accepting the null hypothesis. A p-value greater than 1 or less than 0 represents an erroneous Two-tail (Ha: μ ≠ H0), Significance Level, α: If you want to know the worth of your used electronics, laptops, computers, tablets, phones, iPhones, iPads, or TV’s our calculator is the place to go! We then use df, along with the test statistic, to calculate the p-value. Contribute to SteamDB: Use our token dumper program to help us track hidden games and packages. result. 7 Ways to Extend the Battery Life of a Laptop, CES – Tablets – Samsung Note Pro 12.2, Fuhu Dream Tab, CES – New Laptops – Asus Transformer Duet, Aorus X7. 2.5% Some are very significant, and some are pretty easy to work around. online instant free appraisal process. In some cases it’s a fraction of the capabilities, meaning it’s a fraction of the expense. This is very bad news if you are buying something new, but good news if you are selling your old PC. This can be left-tail (Ha: μ < H0), right-tail (Ha: μ > H0), or two-tail (Ha: μ ≠ H0) testing. The most common is in preparation for a sale. and the right-tail (greater than) possibilities. you get a p-value of .0062 or of freedom, df= 10 - 1= 9. This therefore is easier if you have access to the PC you are trying to determine the worth of. Does anybody think it would be possible to make a PC value calculator? the narrower the range we have for accepting the null hypothesis. Instead I looked up the individual components and determined what each item is worth. If that we can reject the claimed hypothesis. Please note that this principle is gradual (meaning advancement slows not stops) and the end of Moore’s Law also gives manufacturers other ways to optimize and improve electronics they didn’t or couldn’t before the end of this. The p-value represents the probability of a null hypothesis being true. claimed hypothesis. Either one that queried actual values (eBay or something) or just used estimated values based on … This is why it needs to be doubled. As the device becomes technologically obsolete they all lose some value. This should be a fair and simple way to share the fair market value with a prospective buyer. When the sample size is large, we use the Z-distribution to calculate the It’s intended as a fair price to set for a desktop system. At Gadget Value we made the point to write one of the very few (free) calculators to determine what your laptop is worth. measure that tells us how far the actual data results obtained are from the claimed data (from the null hypothesis). Because this is two-tail hypothesis testing, we double this value and get 0.617 or 61.7%. In others it’s actually very comparable to a new one. The corresponding p-value is .6915. with 99% confidence. Left-tail (Ha: μ < H0) The seller should know (roughly) what it’s worth or what to ask for it. While I don’t directly ask this (I determine this by the individual components) there is more than one type of laptop. We wrote this for anybody, but especially non-technical people, to be able to easily and quickly get an accurate idea of what a personal computer is worth. 5% The sample size is 10, so we are going to look up the p-value based on the T-distribution table. This affects all forms of electronics, including phones and tablets as well though. Here are the links for PC or desktop valuations, iPhone worth, or the cell phone worth calculator for non-apples. The lower the significance level, The calculator takes into account the condition of the equipment. on its system configuration and condition. and believe the actual amount is much greater (μ > 4). This is intended as part of a complete PC with all the components, preferably working, but it is still useful functional for a broken one assuming the components are present. standard normal distribution (Z-distribution) to look up the p-value or we use the t-distribution to look up the p-value. This calculator is accurate enough to use for financial inventory, and has been used to set a fair sale price of used electronics in cases where negotiating doesn’t make sense. This appraisal includes the desktop (box), monitor, keyboard, & mouse, but not the printer or office furniture (if any). you believe that the average is much less than this (Ha: μ < 32). You can obtain a whole bunch of data points for a given scenario, but A point to know is that p-values are probabilities; therefore, they must be between 0 and 1. It wasn’t meaningful to look at the various models and list the costs in a simple chart. This is why the sample size is very important. P-value from Z score. Let's go through a few examples on calculating the p-value. All rights reserved. It took a lot of time, and was a project I took over from a prior entrepreneur and greatly improved the accuracy of. I don’t promise perfection, but it should be suitable for most financial purposes. In this case, we calculate the degrees of freedom, df= n-1. Note: If you require the full statistical test calculators, then you should go here. This process is quick, easy, and fairly accurate. This translates from technobabble as computers become twice as powerful every 18 months, but this has gradually changed to more like once every 5 years now. What is the p-value? If the significance level is 10% and the p-value is lower than this amount, this means that we can accept the null hypothesis with If the sample is greater than 30 (n>30), we consider this a large sample size. Furniture (such as a computer desk) isn’t usually transferred with private sales of desktop systems, though there is no reason it cannot happen. The hypothesis testing type gives us a frame of reference. On one hand electronics drop in value once used, but on the other there is a reason they are still frequently stolen for money! However, since this is right-tail hypothesis testing, to calculate the actual p-value, we must take 1 and OuterVision Power Supply Calculator is the most accurate PC power consumption calculator available and is trusted by computer enthusiasts, PC hardware and power supply manufacturers across the Globe. null hypothesis with 95% confidence. Advancement in PC technology has slowed radically. hypothesis testing type (left tail, right tail, or two-tail), and the significance level (α). 10% Enjoy your free custom Valuation! .62%. The first thing is that this is left-tail hypothesis testing. This should be a fair and simple way to share the fair market value with a prospective buyer. Select the picklist below to get started. Should you wish to sell it there is a classified ad at the end to copy the appraisal into. a large sample size. You obtain a test If the p-value is less than α, then this represents a statistically significant p-value. It has been used in many appraisals, set the price of many sales, and inventory assessments by accountants. PC’s are impacted more than others. The appraisal is quick and easy. Another Example: Suppose a company states that they receive, on average, 4 customer complaints a year (μ = 4). Copyright © 2020 Gadget Value. I looked at every component I would expect to find, and determined the value of it individually. When I determined the financial input of individual factors for this calculator I also took into account how the pricing varies overtime. Copyright © 2020 Gadget Value. When you're working with data, the numbers of the data itself is not very meaningful, 7 Ways to Extend the Battery Life of a Laptop, CES – Tablets – Samsung Note Pro 12.2, Fuhu Dream Tab, CES – New Laptops – Asus Transformer Duet, Aorus X7. The technology is advancing much slower that in used to be, and laptops, more than other electronics, are still relatively useful when they are older. We bring you a unique calculator for bottleneck and chokepoint problems in your computers. Next, we must know the hypothesis testing type. However if you don’t, or it’s not working, feel free to proceed and see how far you can get. Let's say you locate 10 customers (n=10) to find out their experience and obtain a test statistic of 1.96. How much ram, disk space, etc. This page will calculate the approximate value of your Steam account by looking up your games on your Steam community profile, using the current prices for each game on the Steam store. 0.5% A netbook is very low end (not really a “real computer”), typically with an SD card as vs a traditional one. subtract this from .95, which gives us a value of .025. This accounts for both the left-tail (less than) This means that if the p-value is lower than the 5% significance level, this means that we can accept the But we want to find the area beyond this. Perhaps one already exists? Right-tail (Ha: μ > H0) Therefore, we look up the p-value on the Z-distribution table. We'll assume you're ok with this, but you can opt-out if you wish. This calculator calculates the p-value for a given set of data based on the test statistic, sample size, hypothesis testing type (left-tail, right-tail, or two-tail), and the significance level.
