A long day in school

The book discusses extended day success stories in public schools throughout the country, the impact on teachers and families, and benefits for English language learners and children with learning disabilities. Introduction Since the end of World War II, most American children have attended school for approximately six and a half hours per day. Most dismissal bells ring around 2:

Moving Averages - Simple and Exponential Introduction Moving averages smooth the price data to form a trend following indicator. They do not predict price direction, but rather define the current direction with a lag.

Moving averages lag because they are based on past prices. Despite this lag, moving averages help smooth price action and filter out the noise.

These moving averages can be used to identify the direction of the trend or define potential support and resistance levels. Click the chart for a live version Simple Moving Average Calculation A simple moving average is formed by computing the average price of a security over a specific number of periods.

Most moving averages are based on closing prices. A 5-day simple moving average is the five-day sum of closing prices divided by five. As its name implies, a moving average is an A long day in school that moves. Old data is dropped as new data comes available.

This causes the average to move along the time scale. Below is an example of a 5-day moving average evolving over three days. The second day of the moving average drops the first data point 11 and adds the new data point The third day of the moving average continues by dropping the first data point 12 and adding the new data point In the example above, prices gradually increase from 11 to 17 over a total of seven days.

Notice that the moving average also rises from 13 to 15 over a three-day calculation period. Also, notice that each moving average value is just below the last price.

For example, the moving average for day one equals 13 and the last price is Prices the prior four days were lower and this causes the moving average to lag.

The weighting applied to the most recent price depends on the number of periods in the moving average. You need far more than 10 days of data to calculate a reasonably accurate day EMA. There are three steps to calculating an exponential moving average EMA.

First, calculate the simple moving average for the initial EMA value. An exponential moving average EMA has to start somewhere, so a simple moving average is used as the previous period's EMA in the first calculation.

Second, calculate the weighting multiplier. Third, calculate the exponential moving average for each day between the initial EMA value and today, using the price, the multiplier, and the previous period's EMA value. The formula below is for a day EMA.

The Weighting Multiplier A period exponential moving average applies an A period EMA can also be called an A period EMA applies a 9.

Notice that the weighting for the shorter time period is more than the weighting for the longer time period. In fact, the weighting drops by half every time the moving average period doubles. If you want to use a specific percentage for an EMA, you can use this formula to convert it to time periods and then enter that value as the EMA's parameter: The SMA calculation is straightforward and requires little explanation: The exponential moving average in the spreadsheet starts with the SMA value Memorial Day is an American holiday, observed on the last Monday of May, honoring the men and women who died while serving in the U.S.
