First decide what the benchmark index is (i.e the FTSE, DOW Jones, commodities index etc). Then plot the benchmark returns against the stock returns. Then add a straight line of best fit. The beta is the slope of the trendline

What does BETA indicate?
Beta is a measure of a stock's volatility. The price of a stock with a beta of 1.0 rises and falls on average with the overall market. A beta greater than 1.0 could mean larger prices fluctuations, and a beta of less than 1.0 indicates a more tame stock. For example, if Company A has a beta of 1.2 and the market goes up 10% in a given period of time then Company A should increase about 12% in value. If the market falls 20% then Company A's stock price should drop 24%.

Why is beta the correct measure of a stock riskiness?
Beta measures a stock's volatility (the swings up and down in price). The market as a whole has a beta of 1.0, but each stock is determined a beta value from a history of it's stock movements. Riskiness equates to the stock losing value and high beta stocks are more prone to falling faster.
How can I calculate the portfolio beta by weighting individual stock's betas?

How can you measure volatility using beta?
You can use Beta to measure market volatility because of beta is the elasticity of a stock change as a result of a change in the market. That is, Beta of a sotck is found by comparing the senstivity of a stock's return to the fluctuations in the market.Beta is found by dividing the product of the covwariances of the stock and market retun by the variance of the market.The bench marks of betas are as followed:a risk free investment such as a Tbill (that is guaranteed a return) will have a beta of 0.A portfolio with risk equivalent to the market has a beta of 1.Given those two bench mark, you can gauge at the volatility of the stock/investment by comparing its beta with those two extremes.
What would make a firm's beta increase?
The beta of a firm's stock is dependent on the volatility of the stock relative to the overall market. So if the stock's volatility increased relative to the overall market, it's beta would increase as well.
Beta?
In my last post I discussed an investment metric known as alpha. Alpha is a gauge of risk-adjusted returns provided by a portfolio manager. Alpha isn’t the only measure of a stock or portfolio’s risk profile. Another one is called beta. Beta measures a stock’s volatility in comparison to the overall market. A beta value of 1 is assigned to the overall market. So a stock that has a beta of one would be considered to move in lockstep with the overall market. If the market were to go up by 10%, the stock should also move by the same amount in the same direction. A stock that moves less than the overall market would have a beta less than one. A beta greater than one indicates a stock that moves in the same direction as the overall market but in more extreme swings. Beta can be a good figure to use in rule-of-thumb investment decisions but it does have one serious drawback of which investors should be aware. Beta is calculated based on historical price movements relative to the market. Because of this method of calculation it doesn’t take into account any new information about the underlying fundamentals of the company. Due to this limitation, beta should never be used in a vacuum. Remember, statistics like alpha and beta can provide guideposts to help you evaluate an investment manager or the risk of a particular stock but they shouldn’t be relied upon to replace the hard work of fundamental analysis. It is the key things going on with a company’s balance sheet and income statement that are the true underpinnings of the stock’s valuation. Keep this in mind when evaluating stocks or portfolios and you’ll be in good shape. I’m not saying that statistics like alpha and beta should be ignored; they’re great tools. Just don’t let them be the only tools you use when making investment decisions.
