Median Empire

Examples of Median Empire in the following topics:

• The Achaemenid Empire

  • Under Cyrus the Great and Darius the Great, the Achaemenid Empire became the first global empire.
  • The Achaemenid Empire, c. 550-330 BCE, or First Persian Empire, was founded in the 6th century BCE by Cyrus the Great, in Western and Central Asia.
  • By the 7th century BCE, a group of ancient Iranian people had established the Median Empire, a vassal state under the Assyrian Empire that later tried to gain its independence in the 8th century BCE.
  • Around 550 BCE, Cyrus II of Persia, who became known as Cyrus the Great, rose in rebellion against the Median Empire, eventually conquering the Medes to create the first Persian Empire, also known as the Achaemenid Empire.
  • Cyrus II of Persia, better known as Cyrus the Great, was the founder of the Achaemenid Empire.

• The Persian Wars

  • The Persian Wars (499-449 BCE) were fought between the Achaemenid Empire and the Hellenic world during the Greek classical period.
  • The Lydians of western Asia Minor conquered the cities of Ionia, which put the region at conflict with the Median Empire, the precursor to the Achaemenid Empire of the Persian Wars, and a power that the Lydians opposed.
  • In 553 through 550 BCE, the Persian prince Cyrus led a successful revolt against the last Median king Astyages, and founded the Achaemenid Empire.
  • Nonetheless, the Ionian Revolt remains significant as the first major conflict between Greece and the Persian Empire, as well as the first phase of the Persian Wars.
  • During this campaign, Mardonius re-subjugated Thrace and forced Macedonia to become a fully submissive client of the Persian Empire, whereas before they had maintained a broad degree of autonomy.

• The Assyrians

  • The Assyrian Empire was a major Semitic kingdom, and often empire, of the Ancient Near East.
  • Following the fall of the Akkadian Empire, c. 2154 BCE, and the short-lived succeeding Sumerian Third Dynasty of Ur, which ruled southern Assyria, Assyria regained full independence.
  • However, a shift in the Assyrian's dominance occurred with the rise of the Middle Assyrian Empire (1365 BCE-1056 BCE).
  • Additionally, during this period, Assyria overthrew Mitanni and eclipsed both the Hittite Empire and Egyptian Empire in the Near East.
  • After its fall (between 612-605 BCE), Assyria remained a province and geo-political entity under the Babylonian, Median, Achaemenid, Seleucid, Parthian, Roman, and Sassanid Empires, until the Arab Islamic invasion and conquest of Mesopotamia in the mid-7th century CE when it was finally dissolved.

• Art and Architecture of the Achaemenid Empire

  • The Achaemenid Empire was known for its eclectic style of art and architecture synthesized from many foreign influences between 550 and 330 BCE.
  • The quintessential characteristic of Persian art and architecture is its eclectic nature, combining elements of Median, Assyrian, and Asiatic Greek styles.
  • This event brought an end to the Achaemenid Empire and made Persepolis a Macedonian province.
  • Features 5th century BC carving of Persian and Median soldiers in traditional costume.
  • The Medians are wearing rounded hats and boots.

• Median and Mean

  • State whether it is the mean or median that minimizes the mean absolute
  • State whether it is the mean or median that minimizes the mean squared deviation
  • The mean and median are both 5.
  • Absolute and squared deviations from the median of 4 and the mean of 6.8
  • The distribution balances at the mean of 6.8 and not at the median of 4.0

• Median

  • The median is the middle value in distribution when the values are arranged in ascending or descending order.
  • There are three main measures of central tendency: the mode, the median and the mean .
  • The median divides the distribution in half (there are 50% of observations on either side of the median value).
  • In a distribution with an odd number of observations, the median value is the middle value.
  • Comparison of mean, median and mode of two log-normal distributions with different skewness.

• Skewness and the Mean, Median, and Mode

  • The mean, the median, and the mode are each 7 for these data.
  • In a perfectly symmetrical distribution, the mean and the median are the same.
  • The mean is 6.3, the median is 6.5, and the mode is 7.
  • The mean and the median both reflect the skewing but the mean more so.
  • The mean is 7.7, the median is 7.5, and the mode is 7.

• Statistical Literacy

  • They reported the mean household income and the median age of theatergoers.
  • What might have guided their choice of the mean or median?
  • Therefore the mean is probably higher than the median, which results in higher income and lower age than if the median household income and mean age had been presented.

• Robust statistics

  • (a) Which is more affected by extreme observations, the mean or median?
  • The median and IQR are called robust estimates because extreme observations have little effect on their values.
  • The median and IQR do not change much under the three scenarios in Table 1.27.
  • The median and IQR are only sensitive to numbers near Q1, the median, and Q3.
  • 1.35: Buyers of a "regular car" should be concerned about the median price.

• Which Average: Mean, Mode, or Median?

  • The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of $\{3, 5, 9, \}$ is 5).
  • The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of $\{3,5, 9\}$ is 5).
  • The mean is 2.5, as is the median.
  • In this case, the arithmetic mean is 6.2 and the median is 4.
  • Unlike mean and median, the concept of mode also makes sense for "nominal data" (i.e., not consisting of numerical values in the case of mean, or even of ordered values in the case of median).
