Question

Need help filling two of the blanks for question one and need help with calculating question 2, I used the mean as 4.7333 and the 2nd observation is 3, so according to the formula for squared deviation I did (3-4.7333) = -1.7333^2 = 3.0044, also tried -3.0044 and both were wrong so could you please explain thoroughly? Thanks in advance

Every collection of data has a distribution associated with it, and every distribution has spread. In statistics, a numerical value that conveys the idea of spread for a data set is called a measure of ability The range is the numerical distance between the largest value in the data set and the smallest value in the data set (largest value smallest value). The interquartile range measures the spread of the data within the middle 50% of the ordered data The term refers to the difference between each observed value in a data set and the mean of the data set, and is computed (x-xbar) The sample variance is the approximate average of the squared deviations from the sample mean. The sample standard deviation is derived from the variance and is in the units as the raw data. 0.3 Points Question 2 of 6 Hours Exercising per Week 0 1 2 3 4 5 6 7 8 9 Number of Hours Accepted characters: numbers, decimal point markers (period or comma), sign indicators spaces (e.g., as thousands separator, 5 000), "E" or "e" used in scientific n NOTE: For scientific notation, a period MUST be used as the decimal point marker. Complex numbers should be in the form (a bi) where "a" and "b" need to have explicitly stated values. For example: (1+1it is valid whereas (1+it is not. (0+9) is valid Whereas (9it is not. The average number of hours exercised per week by the participants represented in the dot plot given below is 45 hours. What is the squared deviation between the 2nd observation and the mean of the sample?(do not round)

Explanation / Answer

1) The term deviation score refers to the difference between each observed value in a data set and the mean

(If the answer deviation score didnt work, try wrinting simply 'deviation' or 'delta')

The sample standard deviation is derived from the variance and is in the same unit as the raw data

2) In this question, it is given that the mean of the data is 4.5

Eventhough the mean if calculated, we will get 4.7333, u just try solving it with the given mean

(3 - 4.5)^2 = 2.25

(This value cannot be negative)
