Assessing testretest reliability requires using the measure on a group of people at one time, using it again on the same group of people at a later time, and then looking at testretest correlation between the two sets of scores. This is typically done by graphing the data in a scatterplot and computing Pearsons r.
The use and production of coal is on the decline, pressured by cheap natural gas and policies to promote cleaner sources of energy. In a recent article in The Regional Economist, Regional Economist Charles Gascon and Senior Research Associate Jonas Crews took a deeper look at the future of coal production as a source for both electricity and jobs in the
What''s the Future for Coal?
With this new agreement, we want to give them peace of mind and ensure they can focus on their core business also in the future, says Haidar al Hertani, Managing Director, W#228;rtsil#228; Saudi Arabia.
In 2018, the North American Electric Reliability Corporation (NERC), which oversees reliability of the North American electric grid, warned that an accelerated retirement of coalfired and nuclear power plants over the next several years could lead to power outages, temporary shortfalls in surplus generation, and transmission problems in several regions.

need for pipeline infrastructure, contributes to coals supply stability. Coal also has the unique advantage of being able to be stored onsite, providing weeks or even months of fuel supply at the power plant. This important characteristic contributes to grid reliability, resiliency and reduces fuel supply bottlenecks.
But the combined impacts of coal bans and related measures raise questions about the future of coal use elsewhere, Dotson said. quot;It fits into this mosaic of state actions,quot; he said.

Between federal regulations to restrict carbon dioxide emissions and mercury pollution, cheap natural gas, and concerns about climate change, the coal industry in this country is under threat. Since 2012 nearly 60 coalburning power plants have partially or completely shut down. But the dirty fuel still supplies 40% of our power and is critical, proponents say, for maintaining the reliability
