Do you prefer Kaldi’s or Starbucks? This choice is given to SIUE students every day. Our group chose to conduct an experiment that proves that students prefer Starbucks to Kaldi’s. To ensure we got the best results, we created an eight-question survey, which we used as factors in our descriptive statistics and regression outputs. They included: how old are you, what school are you in, what gender are you, do you prefer Starbucks or Kaldi’s, do you enjoy a treat with your drink, do you prefer a store

Task 1 - [10 Marks] The file Task1-Data.xlsx contains the results for the questions in Task 1. a. Results are as shown in Task1-Data.xlsx workbook (a.). b. Results are as shown in Task1-Data.xlsx workbook (b.). “Location” and “Ownership” are “Nominal” as they are not numerical and as such they are given a number in its place. The rest of the categorical variables are “Ordinal” as they can be ranked from smallest value to largest. c. In Task1-Data.xlsx workbook (c.) contain the histograms for

During the first round of data collection, 48 recording sheets were distributed over four work days, three shifts per day, and four work areas per shift. There were 109 restocking times reported on the recording sheets. The mean was 7 minutes and 32 seconds. The median was 7 minutes and 37 seconds. During the second round of data collection, 48 recording sheets were distributed over four work days, three shifts per day, and four work areas per shift. There were 110 restocking times reported on

Classification of samples for TDS Prior to the sample analysis, 841 samples were collected from selling agricultural, animal, and aquatic products, and their processed form in markets of nine major cities were classified with nonfat liquid, nonfat solid, fat liquid, fat solid, lipoprotein liquid and alcoholic liquid following the matrix and figuration using food and nutrient data system of the ministry food and drug safety. The classified results are listed in table 1. Method validation The analytical

Introduction Descriptive statistics organize and describe the characteristics of a data set. Researchers are interested in two types of descriptive statistics: central tendency and variability. Measures of central tendency describe the center of a distribution of scores. Common measures of central tendency are the mean, median, and mode. Variability describes the dispersion or spread of scores in a data set. The three commonly reported measures of variability are standard deviation, range, and variance

When people hear the words “life” and “stress” together in the same sentence the words alone may already be causing some to acquire more stress. Stress is very common and known by every living thing and can play a huge role in our lives. We have all experienced stress in some type of form. It is a very unpleasant state of emotional and physiological arousal that people experience in situations that are dangerous or threatening. It may also vary by its definition because it may mean something slightly

For our fall final this year we were assigned a task to collect 100 pieces of data for a survey question of our choice. With that survey question we had to survey 100 students from the same population. After collecting that data we had to input it all into a spreadsheet to find the frequencies for each answer. With those frequencies we then found the mean, median, mode, range, quartile 1, quartile 2, quartile 3, the interquartile range, maximum, minimum, outliers, standard deviation, and a z-score

1) Write the following as an algebraic expression using x as the variable: Twelve less than six times a number   A.  6x – 12 [(Six times a number means 6x, and twelve less mean -12)]  B.  –6x  C.  –12(6x)   D.  12 – 6x 2) Write the following as an algebraic expression using x as the variable: The sum of a number and -8   A.  -8 + x [(let x be the variable number, therefore sum of variable (x) and (-8) would be x-8 or -8 + x)]  B.  -8 - x  C.  x(-8)   D.  -8x 3) Write the following as

Abstract The purpose of this paper is to provide a written report of the five part M&M project. Part one was sampling. We were to purchase 3 bags of M&M and record the color counts of each bag in an Excel spread sheet. For part two we calculated the sample proportions for each color, the mean number of candies per1.69oz bag, created a histogram for the number of candies per bag, use Excel to compute the descriptive statistics for the total number of candies per bag and summarize the information

1 - Produce the relevant descriptive graph and table to summarise the MODE variable (labelled Control: Completes by phone/mail/web). The MODE variable summarises the different ways that each institution completed the survey. Write a paragraph explaining the key features of the data observed through the output. The distribution of the surveyance mode which was conducted for a sample of 2000. The mode is displayed in the above chart. The most common primary mode was the web (53.9%) it was
