How is a sample related to a population? A sample is a subset of a population What is the difference between a parameter and a statistic A parameter is a numerical description of a population characteristic. A statistic is a numerical description of a sample characteristic True or False A statistic is a numerical description of a population characteristic True or False It is impossible to obtain all of the census data about the US population. True or False A population is the collection of some outcomes, responses, measurements, or counts that are of interest. False... A population is the collection all outcomes, responses, measurements, or counts that are of interest. Population or Sample? The salary of each member of a Major League Baseball team Population... It is the collection of the salaries of each member of a MLB team. Population or Sample? A survey of 300 people from an auditorium with 13,000 people. Sample... The collection of the 300 people is the subset of the population of 13,000 people in the auditorium. Population or Sample? The triglycerides level of 10 patients in a clinic with 50 patient Sample... The collection of 10 patients is a subset of the population of 50 patients in the clinic. Population or Sample? The final score of each gamer in a tournament? Population... Because it is the collection of all of the gamers scores in the tournament. Population or Sample? The political party of every US Senator? Population... It is the collection of all of the US Senators political parties. Presentation on theme: "What data set is the collection of all outcomes, responses, measurements, or counts that are of interest?"— Presentation transcript: 1
What data set is the collection of all outcomes, responses, measurements, or counts that are of interest? 2 A Population 3 What is the data set that is a subset or part of a population? 4 A Sample 5 Identify
the Population and the Sample 6 Population: Collection of the responses of all U.
S 7 Identify the Population and the Sample 8 Population: Collection of the responses of all U. S 9 What is a numerical description of a population characteristic? 10 Parameter
11 What is a numerical description of a sample characteristic?
12 Determine whether the numerical value is a parameter or a statistic 13 Parameter. The value $2,940,657,192 is a numerical description of the total player salary for all of the players in Major League Baseball.
14 Determine whether the numerical value is a parameter or a statistic 15 Statistic 20% of Mathematics Majors are minoring in physics is based on a subset of the
population. 16 The freshman class at a university has an average SAT math score of 514.
17 Because the average SAT math score of 514 is based on the entire freshman class, it is a population parameter.
18 What kind of data consists of attributes, labels or 19
Qualitative 20 Determine whether the data are qualitative or quantitative. Explain
21 Quantitative Because ages are numerical measurements.
22 Determine whether the data are qualitative or quantitative. Explain.
23 Quantitative, Because revenues are numerical measurements.
24 If data is qualitative what two kinds of level of measurements an be considered to use?
25 Describe the differences Between Interval and Ratio Levels of Measurement.
26 Interval Data can be: Ordered, and have meaningful differences between data entries. Ratio Data can be: Two data entries can be formed so that one data entry can be meaningfully expresses a multiple of
another. 27 Determine the level of measurement of the data set. Explain.
28 Interval The data can be ordered and meaningful
differences can be calculated, but it does not make sense to say that 87 degrees is 1.16 times as hot as 75 degrees. 29 Determine the level of measurement of the data set. Explain. 30 The data are qualitative and cannot be arranged in a meaningful order. 31 Determine whether the study is an observational study or an experiment
32 Experiment The study apples a treatment (hypothyroidism drug) to the subjects.
33 Identify the population and the sample in the following study.
34 Population: Collection of the prostate conditions of all men Sample: Collection of the prostate conditions of the
20,000 men in study. 35 Determine whether the numerical value is a parameter or a statistic 36 The value 40% is a numerical description of a sample of U.S. adults. 37 Determine whether the numerical value is a parameter or a statistic
38 Parameter The 90% of members that approved the contract of the new president is a numerical
description of all Board of Trustees members. 39 What is the Science of collecting, organizing, and interpreting data in order to make decisions?
40 Statistics 41 Determine whether the numerical value is a parameter or a
statistic
42 Statistics The value 17% is a numerical description of a sample of small business owners.
43 A list of debit card pin numbers
44 Qualitative, Because debit card pin numbers are labels and it does not make sense to find differences between numbers. 45 The final top scores on a video game
46 Because final scores are numerical measurements.
47 Determine whether the study is an observational study or an experiment. 48 Observational study. The study does not attempt to influence the responses of the subjects and there is no treatment.
49 Determine whether the study is an observational study or an experiment. 50 Experiment The study applies a treatment (multivitamin) to the subjects.
