The statistical values such as mean, Median and mode gives measure of centre of a data, while the midrange gives information about the spread. Hence, the statistical measures are :

Given the data :

Mean = [Σx ÷ n]

Mean = (24+26+89+16+38+69+93+3+1+80+49) / 11

Mean = (488 ÷ 11) = 44.36

The median :

Median = 0.5(11 + 1) = 6th term

Median = 38

The Mode :

The most frequently occurring value in a distribution ; since each the value occur just one, then there is no single mode value.

The midrange :

Midrange = (93 - 1) / 2

Midrange = 92/2 = 46

Therefore, the midrange is the value of the range divided by 2.

The standard deviation of the data sample give the degree of spread of the data. Hence, the standard deviation of the data is 0.08

The sample standard deviation is defined as :

The mean :

[tex] \mean = \frac{0.4 + 0.24 + 0.22 + 0.26 + 0.34}{5} = 0.292[/tex]

The Variance :

[tex]\sqrt {\frac{(0.4 - 0.292)^{2} + (0.24 - 0.292)^{2} + (0.22 - 0.292)^{2} + (0.26 - 0.292)^{2} + (0.34 - 0.292)^{2}}{5 - 1}} = 0.00572[/tex]

The standard deviation :

[tex]\sqrt {\frac{(x - \mean)^{2} }{n-1}} [/tex]

[tex]\sqrt {0.00572} = 0.0756[/tex]

Therefore, the standard deviation of the data sample is 0.08.

Answer:

Percentile of 20th = 20

Percentile of 25th = 22.5

Percentile of 65th = 28

Percentile of 75th = 29

Explanation:

Sort the numbers in ascending order:

15,20,25,25,27,28,30,34

i = P/100 * N ( i index is the position of the number. Index 1 = 15, index 2 = 20, and so on)

Index of the 20th percentile:

20/100 * 8 = 1.6

Round 1.6 to the next integer = 2

The second number I=20

The 20th percentile is 20

Index of the 25th percentile:

25/100 * 8 = 2

Because 2 is an integer the percentile of 25th is the average of I=20 and I=25

(20+25)/2=22.5

The 25th percentile is 22.5

Index of the 65th percentile

i = 65/100 * 8 = 26.5 = 5.2

Round to the next integer = 6

The 65th percentile is 28

Index of the 75th percentile

I = 75/100 * 8 = 6

Since 6 is an integer (28+30)/2 = 29 percentile

Observation Tools

Programs must select either the Environment Rating Scale (ERS) and/or the Classroom Assessment Scoring System™ (CLASS™) observation tool and complete the required training for that tool.

Classroom Assessment Scoring System (CLASS)

CLASS is an observation tool that measures the effectiveness of classroom interactions among teachers and children, including emotional support, classroom organization and instructional support. These daily interactions promote children’s social and cognitive development.

CLASS observation tools have been developed for Infant, Toddler, Pre–K, K–3, Upper Elementary and Secondary age groups. At every age level, CLASS focuses on interactions that support learning.

The CLASS Self Assessment Form can be used by directors and teachers to internally identify strengths and focus on changes the program plans to make. Access to the CLASS Self Assessment form.

Environment Rating Scales (ERS)

ERS is an observation tool that assesses the quality of interactions between adults and children, including classroom schedules, materials and spaces available and accessible to children. The use of ERS is a widely accepted method of evaluating and improving the quality of home– and center–based programs.

Environment Rating Scales is broadly defined and currently includes the Early Childhood Environment Rating Scale-Third Edition (ECERS-3), the Infant Toddler Environment Rating Scale-Third Edition (ITERS–3), and the Family Child Care Environment Rating Scale–Revised (FCCERS–R).

The ERS Self Assessment Form can be used by directors and teachers to internally identify strengths and focus on changes the program plans to make. Access to the ERS Self Assessment form.
