Terms in this set (24)nominal level of measurement The nominal level of measurement is characterized by data that consist of names, labels, or categories only. The data are qualitative and cannot be ranked or ordered. ordinal level of measurement The ordinal level of measurement applies to qualitative data that can be arranged in some order (such as low to high). It generally does not make sense to do computations with data at the ordinal level of measurement. A survey asked people about their party affiliation and recorded the responses as 1 for Democrat, 2 for Republican, 3 for Independent, and 4 for anything else. The survey found that the average (mean) party affiliation is 2.5. This statement does not make sense because, while the data are coded with numeric quantities, the data are not quantitative in nature. Thus, it does not make sense to find an average of the responses. Los Angeles reached a temperature of 100degreesF today, which was twice as hot as the 50degreesF in Denver. This statement does not make sense because, while the data are quantitative, the corresponding measurement has an arbitrary zero point, implying that ratios between values are not meaningful. The types of climates for different regions (tropical, temperature, arid, etc.) They are qualitive because they don't count or measure anything Data come in ___ basic types, qualitative and quantitative. Qualitative (or categorical) data consist of values that can be placed into nonnumerical categories. Quantitative data consist of values representing counts or measurements. two The weight classes of professional boxers (lightweight, middleweight, etc.) ordinal the salaries (in dollars) of actor ratio customer satisfaction ratings (unsatisfied, satisfied, very satisfied) ordinal A movie with a 4 star rating is twice as good as one with a 2 star rating the ratio level of measurements does not apply What is statistics? the science of conducting studies to collect, organizes, analyze, summarize and draw conclusions from data numerical data statistics are _________ ____ that we work with -- it's the science of using these data to learn about our world and make conclusions observational unit the object that we are collecting information from is called the ___________ _____ data (or variable) The different types of information we collect for each student is called: What are the two distinct types of data?

be grouped into different categories Description of Quantitative (Numerical) - takes on numerical values & refer to the quantity, size What type of data can take on any value in a given interval? (height, time it takes for you to talk from your room to your car) continuous What type of data can take on only particular, distinct values and not other values in between? (number of steps you take from your room to your car) discrete The population is the: complete set of people or things being studied a population parameter is: a number that describes a characteristic of the population a sample is the: set of people or things from which the data are obtained a sample statistic is: a number that describes a characteristic of a sample raw data is the individual measurements collected Students also viewedHomework 2.115 terms rachelannrhodes Homework 2.25 terms rachelannrhodes Homework 2.310 terms rachelannrhodes final quan40 terms yoshiiimoto Other sets by this creatorlab study guide42 terms zeineba Unit 6 Medical Administration48 terms zeineba Unit 5 - Phlebotomy and Capillary Puncture50 terms zeineba unit 4: laboratory tests70 terms zeineba Verified questions

geometry Felicity asked 100 students how they cam to school one day. Each student walked or came by bicycle or came by car. 49 of the 100 students are girls. 10 of the girls came by car. 16 boys walked. 21 of the 41 students who cam by bicycle are boys. What is the probability that a student walked to school given that the student is a girl? Verified answer algebra Carry out the indicated operations in the agreed-upon order.\ $$ 11-6+4 $$ Verified answer
linear algebra Suppose that $\lambda_{1} \neq \lambda_{2}$ are eigenvalues of a $2 \times 2$ matrix A with associated eigenvectors $u_1$ and $u_2$. Prove that $\operatorname{det}(U) \neq 0$ for $$ U=\left[\begin{array}{ll} \mathbf{u}_{1} & \mathbf{u}_{2} \end{array}\right] $$ .

A distinguishing feature of ordinal data is that the categories it uses are ordered on some kind of hierarchical scale, e.g. high to low.
Is ordinal level of measurement qualitative?The ordinal scale contains qualitative data; 'ordinal' meaning 'order'. It places variables in order/rank, only permitting to measure the value as higher or lower in scale. The scale cannot generate a precise comparison between the two categories.
Are data at the interval level of measurement quantitative or qualitative quizlet?Data at the interval level of measurement are quantitative only. Data at this level can be ordered and differences between data entries are meaningful, but a zero entry is not an inherent zero. Data at the ratio level of measurement are quantitative only.
Is qualitative ordinal or nominal?Nominal- and ordinal-scale variables are considered qualitative or categorical variables, whereas interval- and ratio-scale variables are considered quantitative or continuous variables. Sometimes the same variable can be measured using both a nominal scale and a ratio scale.
