There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (“state” and “statistics” come from the same Latin root, “status&rdquo and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modern descriptive statistics. From the influence of the father came modern inferential statistics, which is based squarely on theories of probability. VCO/s9AL
Descriptive statistics involves tabulating, depicting, and describing collections of data. Theses data may be quantitative, such as measures of height, intelligence, or grade level—variables that are characterized by an underlying continuum—or the data may represent qualitative variables, such as ***, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is a tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data. (0S7
Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child: the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population. "

It is possible to persuade mankind to live without war? War is an ancient institution which has existed for at least six thousand years. It was always wicked and usually foolish, but in the past the human race managed to live with it. Modern ingenuity has changed this. Either Man will abolish war, or war will abolish Man. For the present, it is nuclear weapons that cause the gravest danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in massacre, but by arbitration in accordance with agreed principles of law. It is not easy to change age-old mental habits, but this is what must be attempted.

There are those who say that the adoption of this or that ideology would prevent war. I believe this to be a profound error. All ideologies are based upon dogmatic assertions which are, at best, doubtful, and at worst, totally false. Their adherents believe in them so fanatically that they are willing to go to war in support of them. c1i7Rc{q
The movement of world opinion during the past two years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the international sphere, but the spirit in which they are being approached is a better one than it was some years ago. It has began to be though, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between East and West, but between Man and the H-bomb. SDkN

The acknowledged “King of Ragtime” was the black pianist and composer Scott Joplin. Joplin (1868-1917), originally from Texarkana, Texas, began his career as an itinerant pianist. By 1885 he was in St. Louis, playing in honky-tonks and sporting houses. He went to Chicago briefly (1893) to try his luck in the entertainment halls that had sprung up around the Word’s Fair, then in 1894 to Sedalia, Missouri, to stay until the turn of the century. His first published rag, Original Rags, came out in March, 1899; later the same year appeared Maple Leaf Rag, named for a saloon and dance hall in Sedalia. The work has an instant and resounding success, and by the time of his death Joplin had published more than thirty original rags, and other piano pieces, songs, and arrangements. He had even larger aims: in 1902 he finished a ballet score called Rag Time Dance, and in 1903 the opera A Guest of Honor, unpublished and now apparently lost, in 1911 came another opera, Treemonisha. The artistic success of these larger works is debatable, but that of Joplin’s piano rags is not; they can only be described as elegant, varied, often subtle, and as sharply incised as a cameo. They are the precise American equivalent, in terms of a native style of dance music, of minuets by Mozart, mazurkas by Chopin, or waltzes by Brahams. They can both be lovely and powerful, infectious and moving-depending, of course, on the skill and stylishness of the pianist, for they are not easy music technically and they demand a clean but “swinging” performance. s
