In simple terms, it tells you how spread out a collection of data points are. positive alpha is considered to be underpriced. In statistics, standard deviation is a measure of how dispersed a set of data is relative to its mean. negative alpha is considered to be a good buy.ĭ. zero alpha is considered to be a good buy.Ĭ. : Is the standard deviation of all possible sample average of the volume, which is called the standard error of the mean, depends on the standard deviation of.
positive alpha is considered overpriced.ī. According to the Capital Asset Pricing Model (CAPM), a security with aĪ. Only unanticipated events would affect the return. The ei term has an expected value of zero. The ei term represents the impact of unanticipated firm-specific events.
The textbook discusses a model in which macroeconomic events are used as a single index for security returns. the impact of unanticipated firm-specific events on security i's return. the impact of changes in the market on security i's return. the impact of anticipated firm-specific events on security i's return.Į. the impact of anticipated macroeconomic events on security i's return.ĭ. I have measurements for multiple devices, and have their mean and sd values. ref The range of cells containing the complete data. RANK.AVG (number, ref, order) number The cell containing the data point you want to rank. This is really easy to do with the RANK AVERAGE function. the impact of unanticipated firm-specific events on security i's return.Ĭ. The first step to create a QQ plot in Excel is to rank the data in ascending order (from smallest to largest). the impact of unanticipated macroeconomic events on security i's return.ī. In the single-index model represented by the equation ri = E(ri) + βiF + ei, the term ei representsĪ. The slope of the regression line, β, estimates the volatility of the stock versus the volatility of the market, and the α estimates the intercept. When doing so, the slope of the regression line is an estimate ofĭ. Analysts may use regression analysis to estimate the index model for a stock. positive because of economic forces that affect many firms.Įconomic forces, such as business cycles, interest rates, and technological changes, tend to have similar impacts on many firms. negative because of economic forces that affect many firms. positive because of economic forces that affect many firms.Į. positive because of Exchange regulations.Ĭ.
#Excel average and standard deviation scatter plot code
Then, with the code in the link above, you could use FunFun add-in to load the chart directly into your excel using the URL above.TERMS IN THIS SET (73) Covariances between security returns tend to beī. Minimum Maximum Lower quartile Higher Quartile Median So in order to draw this chart, your data should look like this. In this case, I used quartile and median to reveal the data. But you need to make some modification to your data. The box plot could give the readers more information about your measurements. Here is the code that I used in the Funfun Online Editor: You could use Funfun to write and run JavaScript code in Excel, so that drawing a box plot like this would be easier in Excel. While Excel doesn't have original box plot support, you could draw this kind of chart easily using JavaScript libaries like HightCharts.js that I'm using for this sample. I made a sample for your problem and it looks like this. But if you have more devices, I recommend you to use Box Plot. If you just have two or three devices and their data, you could use a Normal distribution or Bell curve to plot your mean and standard deviation.
