INVESTIGATION ONE: METHODOLOGY + EXPERIMENTAL DESIGN

Question 1

METHODOLOGY

Question 2

define the aim of the research.

Answer 2

• to establish whether there is a significant negative correlation between an increased chronological age and sleep quality,
• furthering literature that evidences disrupted circadian rhythms, that govern sleep patterns, regularity, continuity + readiness, in older adults (Kim et al., 2022).

Question 3

describe the experimental design + what this means for conclusions drawn.

Answer 3

• quasi-experimental design - as chronological age was a pre-existing, naturally occurring condition, not manipulated by the researcher.
• ∴ in tandem w, the lack of random allocation, means that causal conclusions regarding an increased chronological age + lower levels of sleep quality must be
  interpreted tentatively

Question 4

identify the IV and how it was operationalised within the experimental design.

Answer 4

• age operationalised as chronological age, a quasi-IV
• chronological age has greater generalisability, more ease + practicality, + cost-effectiveness in quantifying than biological age.
• biological age which requires expensive, invasive lab equipment to assess, impractical to the researcher + limiting construct and ecological validity .

Question 5

identify the DV and how it was operationalised within the experimental design.

Question 6

what other data was collected for greater inferential validity?

Question 7

describe the sample size.

Question 8

describe the sampling technique.

Question 9

describe the resulting demographic obtained in this research.

Question 10

describe the materials used.

Question 11

describe the standardised procedure.

Question 12

describe the data collected.

Question 13

briefly discuss the inferential test used.

Question 14

briefly describe the pilot study and the results of such.

Question 15

briefly discuss the ethical considerations within the study.
