Identify two problems with the use of the respondent mean as an imputed value for item-missing data in surveys
The two problems with the respondent mean to use as the input value for an item missing data are as follows:
-The first problem is that the thing missing data can reduce the power of statistics, which means the probability that the data will reject the null hypothesis. Also, the lost data has the least chance that it can be used as a representative of the sample.
-The use of respondent means when the imported value for an item is missing main complicate the analysis for any study. It might threaten the validation of any trial and ultimately lead to any invalid conclusions. Moreover, it can lead to biases in estimations of different perspectives.

Discussion: When doing surveys for research, what can we do regarding missing data in our questionnaires Compare the following techniques and suggest a new alternative: -replacing the missing value with a value from a similar respondent -if there are other similar questions to the one with missing data, use the answers to the other similar questions as a guide to determine the replacement value -use the mean of a subsample of the respondents with similar characteristics that answered the question...
PRACTICE PROBLEMS 18. Use Boyle's law to solve for the missing value in each of the following: a. P1 350.0 torr, V1200.0 mL, P, = 700.0 torr, V2 = ? b. V 2.4 x 105 L, P2 180 mm Hg, V, = 1.8 × 103 L, P =? 19. Use Charles's law to solve for the missing value in each of the following: a. V1-80.0 mL, Tl = 27°C, T2 = 770C, V,-? b. V1 = 125 L.V2-85.0 L, T,...

use R studio A missing value in R is denoted by NA. Missing values are different from other values in R in two ways: 1. Any computation involving a missing value will return a missing value. 2. The is.na function will return TRUE if a value is missing and FALSE otherwise. a) Enter the following code into RStudio. > x <- c (1, 4, 7, NA, 12, 19,15, 21, 20) b) Add an appropriate comment to the above code. Try to find the mean of x. d) Use is.na...
