Answer #1

Descriptive statistics are Numbers that summarize and describe data

Answer :- here Option b is correct answer

Conclusion :- Descriptive statistics are brief descriptive coefficients that summarize a given data set, which can be either a representation of the entire or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread).

There are four major types of descriptive statistics:

  • Measures of Frequency: * Count, Percent, Frequency. ...
  • Measures of Central Tendency. * Mean, Median, and Mode. ...
  • Measures of Dispersion or Variation. * Range, Variance, Standard Deviation. ...
  • Measures of Position. * Percentile Ranks, Quartile Ranks.

Which of the following statements best describes the process that characterizes inferential statistics? Descriptive methods are used to characterize the information in a population so that conclusions may be reached regarding samples taken from that population. Descriptive methods are used to obtain parameters that are then used to make inferences about the sample. Descriptive methods are used to obtain statistics that are then used to make inferences about the population. Finite populations are aggregated to obtain (nearly) infinite populations that...

Simplified version: Calculate descriptive statistics for the variable (Coin) where each of the "thirty-five" students in the sample flipped a coin 10 times. Find the mean and the standard deviation. Note: This is a Binomial Distribution problem, NOT a Binomial Experiment where the occurrences are recorded or provided, nor are individual trials needed unless you are calculating the success for each coin toss which is not what is being asked for in the question. Just the Mean and Standard Deviation......

This project is related to statistical inference about the difference between two population parameters and the analysis of variance. You need to formulate hypotheses testing and confidence estimation as you learned in class. Each group must collect data related to the topic of their choice. You should specify your parameter of interest and the claim, make the hypotheses, perform test calculations and estimation, and make a conclusion. specify your parameter of interest and the claim, make the hypotheses, perform test...

Two methods of Natrella’s research in 1963, A and B, were used in a determination of the latent heat of fusion of ice. The investigator wanted to find out by how much the methods differed. The data (TwoMethods.xlsx) give the change in total heat from ice at -0.72°C to wafer 0°C in calories per gram of mass. (a) Assuming that the population variances are equal, compute the pooled variance of the two sample. (b) Assuming that the population variances are...

Two teaching methods and their effects on science test scores are being reviewed. A random sample of 11 students, taught in traditional lab sessions, had a mean test score of 76.7 with a standard deviation of 3.2. A random sample of 16 students, taught using interactive simulation software, had a means test score of 83.2 with a standard deviation of 6.4. Do these results support the claim that the mean science test score is different for students taught in traditional...
