I see the data and the statistical tasks provided in the image. Let's go through each required calculation step-by-step:

Data Provided

The data set is:

44, 49, 49, 52, 57
51, 54, 44, 52, 43
58, 44, 52, 49, 47
56, 55, 46, 54, 52
58, 45, 51, 58, 53
48, 57, 57, 47, 55
52, 51, 52, 48, 50
48, 47, 58, 49, 50
56, 58, 45, 58, 46
48, 46, 57, 57, 49

This data is organized into 11 rows and 5 columns. Let's proceed with the calculations for each part:

a. Rata-rata (Mean)

The mean is calculated by summing all the values and then dividing by the total number of values.

b. Median

The median is the middle value when the data is ordered from smallest to largest. If there's an even number of values, the median is the average of the two middle numbers.

c. Modus (Mode)

The mode is the value that appears most frequently in the data set.

d. Letak kuartil 3 dan berapa nilai kuartil 3! (Third Quartile and its Value)

The third quartile (Q3) is the median of the upper half of the data.

e. Letak desil 7! (7th Decile)

The 7th decile is the value below which 70% of the data falls.

I'll now calculate each of these.Here are the results for the given statistical tasks:

a. Rata-rata (Mean)

The mean of the data is approximately 51.24.

b. Median

The median of the data is 51.0.

c. Modus (Mode)

The mode of the data is 52 (it appears most frequently in the dataset).

d. Letak kuartil 3 dan berapa nilai kuartil 3! (Third Quartile and its Value)

The third quartile (Q3) value is 55.75.

e. Letak desil 7! (7th Decile)

The 7th decile (D7) value is approximately 54.3.

e. Letak desil 7! (7th Decile)

The 7th decile (D7) value is approximately 54.3.

Do you want more details or have any questions?

Here are 5 additional questions related to the

1. How is the range of the dataset calculated?
2. What is the variance of the dataset?
3. What is the standard deviation of the dataset?
4. What are the values of the first quartile (Q1) and median (Q2)?
5. How many times does the mode value (52) appear in the dataset?

Tip: Quartiles are useful in understanding the spread and skewness of the data, helping in statistical analysis like detecting outliers.
