Down: 1)  any tendency that limits impartial consideration of a question or issue4)  The extent to which repeated measurements on units (for instance people) yield similar results.6)  A study that collects planned information from a sample of individuals7)  refers to any dataset collected by any person other than the one using it. 8) a probability distribution of a statistic that is obtained through repeated sampling of a specific population 12) If a random variable Y has population mean µ and population variance σ squared , then the sample mean, y bar, based on n observations, has an approximate normal distribution with mean µ and variance σsquared / square root n, for sufficiently large n. 14) The whole group that is being studied.16) A number between 0 and 1 used to quantify likelihood for processes that have uncertain outcomes19) The set of divisions that produce exactly 100 equal parts in a series of continuous values20)  how many percentage points your results will differ from the real population value. It is denoted as a tiny percentage allowed for in case of miscalculation. Across: 2)  is used in the design of experiments. When certain factors cannot be controlled, and omitted variable bias has potential to occur,3) The difference between the actual and measured value.5)  A general term for methods of summarizing and tabulating data that make their main features more transparent9) When we do an experiment a large number of times the average result will be very close to the expected result.10) describe the many ways in which statistics derived from observations on samples from study populations can be used to deduce whether or not those populations are truly different.11) A general term for investigations in which the researcher can deliberately influence events, and investigate the effects of the intervention13) a set of methods for collecting, measuring and analyzing data in a way that both respects individual privacy rights and delivers relevant insights.15) Moral principles on which decisions and actions are based17) making predictions based on past observations.18)  The artificial generation of random processes (usually by means of pseudorandom numbers and/or computers) to imitate the behavior of particular statistical models21) The notion that the variability of a sample will differ from another sample of the same population. 22) Rarely do analysts begin working with a new dataset without cleansing it first, it doesn't adhere to the required standards for analysis.23) A selection taken from a larger group (the "population") that will, hopefully, let you find out things about the larger group24) The probability distribution of a statistic calculated from a random sample of a particular size 25) A study in which the objective is to uncover cause-and-effect relationships but in which it is not feasible to use controlled experimentation26) how individuals of a species spread out in the location that they live in27)  A range of values, calculated from the sample observations, that is believed, with a particular probability, to contain the true parameter value28) Data can be distributed (symmetrically distributed with no skew)29) is a third variable in a study examining a potential cause-and-effect relationship.
