Question 1 (5 points)Match the following terms/symbols with their correct definitions____sample____standard deviation (? : population standarddeviation) (s or SD : sample standarddeviation)1.measure of central tendency defining thequantitative average of all raw scores in a dataset/sample/population; the sum of raw scoresdivided by the number of raw scores_____raw score2.measure of central tendency defining themidpoint of a data distribution; as many rawscores in the distribution are below this valueas are above it3.measure of central tendency defining the mostcommonly occurring raw score/value in a dataset; distributions may have 0, 1, or more ofthese4.measure of variability defining the averagesquared differences of raw scores in adistribution from the mean of that distribution5.subset of a population6.measure of variability used to determine howfar raw scores in a data distribution lie fromthat distribution’s mean. Calculated as thesquare root of the variance. Particularly usefulmeasure when data exhibits normal/nearnormal distribution. It’s the “sigma” in “sixsigma” statistical process control techniqueused in many workplace environments.7.graphical method for displaying the shape of adata distribution; particularly useful when thesample/data set/population is large8.tabular display showing values (or intervals ofvalues) and the corresponding number oftimes those values appear (or fall within aninterval) in a distribution9.individual piece of data (“datum”) found withina data set/sample/population10.symbol & variable representing the sum of rawscores in a data set / data distribution11.variable representing the number of rawscores in a data set / data distribution(symbol: “x”)____ n____mean ( x or M : sample mean)population mean)(?:____ ? x____ frequency table____ median____ variance ( ? 2 : population variance)2 : sample variance)____ histogram(s____ mode2.Match each chart definition with that type of chart’s corresponding image:_____ pie chart: Output depicted as percentage of total (100%) output_____histogram (always showing value as x axis and frequency those values appear – often withindefined equally-spaced value intervals- as y axis_____vertical bar chart: input is always x – axis, output is always y – axis_____horizontal bar chart (divided bar): multiple outputs (shown on x – axis) for the same input (shownon y – axis)_____frequency polygon: “line-chart” representation of frequency (y – axis) versus value (x – axis)3. Complete the frequency table above by filling in the frequency of raw scores occurring in eachinterval, using the following data:30, 32, 11, 14, 40, 37, 16, 26, 12, 33, 13, 19, 38, 12, 28, 15, 39, 11, 37, 17, 27, 14, 36Interval 11 – 15: ______Interval 16 – 20: ______Interval 21 – 25:______Interval 26 – 30:_______Interval 31 – 35:______Interval 36 – 40:______4.A survey of 15 randomly selected students responded to the question “How many hours a day do youwork on MATH 106?” as follows: 3, 2, 2, 4, 6, 5, 2, 5, 1, 4, 2, 3, 2, 3, 4 . Which histogram aboveaccurately reflects the frequency distribution of the 15 students’ responses?Question 4 options:Histogram AHistogram BHistogram CHistogram D5. Question 5 (5 points)In a histogram, when the data are symmetrical, what is the typical relationship between the mean andmedian?Question 5 options:A) There’s no relationship between the mean and median of a data distributionB) Value of mean is greater than value of median (mean > median)C) Value of mean is approximately the same as the value of median (mean ? median)D) Value of mean is less than value of median (mean
