In 2010, Rend Lake was designated as an Important Bird Area of Illinois. An adjacent Illinois Artisans Shop & Visitors Center is part of the Illinois State Museum system and is operated by the Illinois Department of Natural Resources. This will help you find the nearest rest area. Click the icon to see your location on the map (your browser might ask for permission). Clicking a rest stop will show its details in the table below the map. I just want to tell you, theres a little problem with the plane. Welcome The following map shows rest areas, welcome centers, turnpike service plazas etc across the US. Swimming beaches at North Marcum and South Sandusky are managed and maintained by the US Army Corps of Engineers. Jack, pick up sweetie, can you hear me Okay. "The lakeshore of Rend Lake extends covers 162 miles (261 km), part of which is preserved as Wayne Fitzgerrell State Recreation Area. Rest Area County Interstate/Milepost Facility Info 34: Gordon I-75 North / MP 308.0 Restrooms open 24 hours Custodians on-premise 7:00 AM-11:00 PM 35: Gordon I-75 South/ MP 320.0. The dam and lake were authorized in 1962, but the lake was not completely filled until March 1973. "Rend Lake is a reservoir, created when the United States Army Corps of Engineers dammed the Big Muddy River. Its elevation is 405 feet (123.4 m) above sea level. The reservoir is up to 35 feet (10.7 m) deep, but its average depth is closer to 9.7 feet (3.0 m). The lake contains 18,900 acres (76 km²) of water, stores 185,000 acre feet (228,000,000 m3) of water, and supplies over 15 million gallons of water per day to 300,000 persons in over 60 communities. "Rend Lake is a 13 miles (20.9 km)-long, 3 miles (4.8 km)-wide southern Illinois reservoir in Franklin and Jefferson Counties near Benton, Illinois. Several common regression techniques can help reduce the influence of outliers on the mean value.Location of rest area: I-57, SB, M/M 79, Whittington If the outlier is confirmed as a valid extreme value, it should not be removed from the dataset. In this distribution the outlier value has increased the mean value.ĭespite the existence of outliers in a distribution, the mean can still be an appropriate measure of central tendency, especially if the rest of the data is normally distributed. However, it has not changed the middle of the distribution, and therefore the median value is still 57 years.ĥ4, 54, 54, 55, 56, 57, 57, 58, 58, 60, 81Īs the all values are included in the calculation of the mean, the outlier will influence the mean value. This value is much higher than the other values, and could be considered an outlier. The mean is more sensitive to the existence of outliers than the median or mode.Ĭonsider the initial retirement age dataset again, with one difference the last observation of 60 years has been replaced with a retirement age of 81 years. designated with stars for more information on individual rest areas. It is important to detect outliers within a distribution, because they can alter the results of the data analysis. The TruckMaster Fuel Finder truck stop locator allows you to find a truck stop by. Outliers are extreme, or atypical data value(s) that are notably different from the rest of the data. The mode is 54 years, the modal class is 54-56 years, the median is 56 years, and the mean is 57.2 years. The data has been grouped into classes, as the variable being measured (retirement age) is continuous. The following graph shows a larger retirement age data set with a distribution which is right skewed. Although there are exceptions to this rule, generally, most of the values, including the median value, tend to be less than the mean value. In a positively skewed distribution it is common for the mean to be ‘pulled’ toward the right tail of the distribution. In a skewed distribution, the median is often a preferred measure of central tendency, as the mean is not usually in the middle of the distribution.Ī distribution is said to be positively or right skewed when the tail on the right side of the distribution is longer than the left side. When a distribution is skewed the mode remains the most commonly occurring value, the median remains the middle value in the distribution, but the mean is generally ‘pulled’ in the direction of the tails.
