- 2six steps in statistical analysis-Defining the problem
-Collecting and assembling relevant information
-conducting an original investigation of the problem
-classifying the data
-presenting the data and analyzing and interpreting the results - 3is concerned with the gathering, classification and presentation of data and the collection of summarizing values to describe group characteristicsDescriptive Statistics
- 4types of summarizing values most commonly used-measure of central tendency position or location
-measure of variability - 5is a single figure which is representative of the general level of magnitudes or values of the items in a set of data.measure of central tendency position or location
- 6is the arithmetic average of all the scores in a distribution.Mean (Me)
- 7is the most frequent scoreMode (Mo)
- 8is a measure which aids the statisticians in making comparisons.Measure of variability
- 9is a measure of the distance from the observations in a data collection to the middle of that collectionStandard Deviation
- 10is the same as the standard deviation except that the square root is not taken.Variance
- 11is the distance between the highest and the lowest score in an array of dataRange
- 12deals with the methods used to describe a population by studying a random sample of that populationInferential Statistics
- 13is any specified group taken as the subjects of the study or researchpopulation
- 14is only a portion or subset of a populationsample
- 15types of inferential statisticsparametric statistics, non parametric statistics
- 16requires that the sample used in the study should come from a population with normal distribution.Parametric Statistics
- 17does not require any assumption regarding the population where the sample is taken.nonparametric statistics
