The Normal Probability Distribution

May 4, 2011

By: Ma’am Clarence

May 4, 2011, 8:00-10:00 in the morning, it’s Statistics time. If our teacher is beautiful, our reporter is also beautiful.

The reporter introduces first the five (5) standard scores. The formula is

           

Z=  x – x

          s

Where:  

            Z= Standard Score

            X= Any row score or unit of measurement

           

X= Mean of the Distribution of scores

S= Standard Deviation

            Second, she now discussed the Normal Curve and Characteristics of the Normal Distribution, the formula can be seen on page 80 of the reference book.

           

            She emphasizes the percentage of distribution in the curve from midpoint to

 -1  = .3435 the same value to + 1 .

             Calexton and I asked the reporter on how about if the curve is between two + 1and +2. What is the percentage of distribution? The reporter was not able to show the table.

            Wow! It’s very advantage because Richard Agapay is with us. He can easily search through internet. The contribution I made is that I found the table at the last part of my book.

            Through the session, it ended with a little knowledge regarding to the topic. I promised to myself that I will study more at home.

            Thank you ma’am Clarence for a delicious snacks.
