- Q3What is the first step in the process of descriptive statistics?Averaging dataClassifying dataGraphing dataCollecting data30s
- Q4Which of the following is a measure of central tendency in descriptive statistics?Coefficient of determinationMeanP-valueStandard deviation30s
- Q5What does the standard deviation measure in descriptive statistics?The central tendency of dataThe dispersion or spread of dataThe significance of resultsThe probability of an event30s
- Q6What is the median in descriptive statistics?The highest value in the data setThe most frequently occurring valueThe average of all the data valuesThe middle value when the data is arranged in ascending or descending order30s
- Q7What is the range in descriptive statistics?The dispersion or spread of dataThe difference between the highest and lowest values in a datasetThe most frequently occurring valueThe average of all the data values30s
- Q8What is the mode in descriptive statistics?The difference between the highest and lowest values in a datasetThe average of all the data valuesThe middle value when the data is arranged in ascending or descending orderThe value that appears most frequently in a dataset30s
- Q9What does the p-value represent in inferential statistics?The probability of obtaining results as extreme as the observed results, assuming the null hypothesis is trueThe average value of a datasetThe dispersion or spread of dataThe significance of results in descriptive statistics30s
- Q10Which measure of central tendency is most affected by outliers?MeanRangeModeMedian30s
- Q11Which type of data is based on observations and facts that come from investigations?Categorical dataDataQuantitative variableMeasurement data30s
- Q12Which of the following is an example of quantitative data?GenderVehicle typeCollege majorTest score30s
- Q13What is the difference between a discrete variable and a continuous variable?A discrete variable represents frequency, while a continuous variable represents a numeric characteristic.A discrete variable is a dependent variable, while a continuous variable is an independent variable.A discrete variable is based on categorical data, while a continuous variable is based on quantitative data.A discrete variable is manipulated by the researcher, while a continuous variable is observed and measured.A discrete variable has a limited number of values, while a continuous variable can take on any value between the lowest and highest points on the measurement scale.30s
- Q14What is the difference between a population and a sample?A population refers to the set of all individuals or entities under consideration, while a sample is a small portion or part of the population.A population is a quantitative variable, while a sample is a qualitative variable.A population represents a continuous variable, while a sample represents a discrete variable.A population is an independent variable, while a sample is a dependent variable.A population is a parameter, while a sample is a statistic.30s
